L4M3 Commercial Contracting Questions and Answers

Express terms are the terms of the agreement which are expressly agreed between the parties. Ideally, they will be written down in a contract between the parties but where the contract is agreed verbally, they will be the terms discussed and agreed between the parties.

Implied terms are terms implied into the contract by the courts. They are not expressly set out in the contract but are taken to be as effective as if they were and as if they had been included from day one of the contract. The express terms and any implied terms together create the legally binding obligations on the parties.

The Unfair Contract Terms Act 1977 (c 50) is an Act of Parliament of the United Kingdom which regulates contracts by restricting the operation and legality of some contract terms. It extends to nearly all forms of contract and one of its most important functions is limiting the applicability of disclaimers of liability. The terms extend to both actual contract terms and notices that are seen to constitute a contractual obligation.

Under this regulation, if a clause within the standard terms in use is considered as ' unfair ' , the clause will be ineffective (or the other party will be entitled to avoid the clause). At court, the clause that is deemed to be unfair will undergo a ' reasonableness ' test or an ' unfairness ' test.

Framework agreements allow for pre-approved suppliers to be used over a contract period with simplified ordering processes. A key benefit is the use of mini-competitions among these suppliers to secure value and innovation without repeating the full tender process. This approach is highly effective in dynamic sectors like telecommunications.

The license can be amended during its lifespan. However, in this case, it already has a clauseallowing for mechanism of variation which sets out who can authorise changes and prohibits any oral variation. Therefore, the agreement between Rock ' s director and MWB credit controller is not an effective variation to the license.

Early market dialogue is used to explore supplier capabilities and gather ideas, particularly in complex or innovative services. Discussing service innovation with suppliers helps the buyer shape better specifications and outcomes. Topics like pricing and contract terms should remain within formal procurement stages to ensure fairness.

KPIs track and control supplier performance, helping to identify and mitigate supply risks such as late delivery or poor quality.

They are a proactive management tool, not a price or sourcing mechanism.

Time-critical requirements, such as daily deliveries by a specific time, should be clearly stipulated as contractual terms. This ensures enforceability and provides a legal basis for remedy in the case of non-performance. Notes on purchase orders or general legislation do not offer the same level of protection or clarity.

Number of on-time deliveries can be quantified, then numerical measures can be applied.

Frequency of on-time deliveries is measured as on-time deliveries as a percentage of total no. of deliveries for period.

LO 2, AC 2.2

An implied term is a term which the courts imply into a contract because it has not been expressly included by the parties. This may be because the parties did not consider it, did not think that any problem would arise in relation to it or simply omitted to include it.

The courts are very reluctant to imply terms into contracts and will only do so in the following circumstances:

- terms implied under statute

- terms implied under common law

- terms implied because of custom or usage

- terms implied due to previous dealings

- terms implied ‘in fact’ or to reflect the parties’ intentions

This scenario is in fact based on a famous case law: Dunlop Pneumatic Tyre Company v New Garage & Motor co [1915] AC 79. In this case law, the House of Lords identified the clause as liquidated damages, and therefore enforceable.

However, if this case had happened in 2015 or afterwards, there would be some legal issues:

- The price agreement is prohibited by Competition Act 1998

- If the agreement is allowed by Competition Act, as in the case Cavendish Square Holding BV (Appellant) v Talal El Makdessi (Respondent), the clause can also be identified as a penalty and it is still enforceable.

An invitation to treat is a legal concept that refers to an indication that a party is open to receiving offers, but it is not an offer in itself. Common examples include advertisements, display of goods in shops, or issuing a tender. It invites others to make offers, which may or may not be accepted.

In a ' battle of the forms ' , both buyer and supplier exchange documents with conflicting terms. The general rule is that the terms of the last document exchanged before performance (e.g., delivery or payment) that is not objected to will govern the contract. An order acknowledgement from the supplier with its own terms, followed by acceptance (e.g., payment), usually constitutes the final word.

An SLA outlines the expected performance levels and includes KPIs and consequences for non-performance (often in the form of penalties or service credits). Force majeure and jurisdiction clauses are typically part of the main contract terms, not the SLA, which is more operational in nature.

A call-off order is raised against an existing agreement or blanket order that sets an overall value limit (£5,000 in this case). Users can “call off” small quantities or values (£50 each time) when required.

Effective KPIs must be SMART: specific, measurable, achievable, relevant, and time-bound. " Effort exerted " is vague and not objectively measurable, making the KPI unsuitable. A better KPI would involve actual cost data or variance against a defined budget.

A lease is a contractual arrangement calling for the lessee (user) to pay the lessor (owner) for use of an asset. Some characteristics of Leases are:

- The right to use the lessor’s asset is granted in exchange for a fee called the lease payment.

- The lease payments are usually paid in installments.

- Leases may be long- or short-term.

- At its inception a lease agreement constitutes a mutually unperformed contract

Though the ownership of the asset is not transferred to the lessee, some responsibilities and risks do. The lessor and lessee may negotiate on who is responsible on maintenance, insurance, etc.

Advantages of using invitation to tender may be as below:

No Nepotism: Tenders or bids are evaluated on the basis of certain predetermined criteria, such asprice, quality and value for money. In other words, the firm offering the highest quality product or service at the lowest price point would win the contract. As most tender documents are opened and evaluated in a public process, I think that there remains little room for nepotism or favoritism of any kind.

Value for Money: From the perspective of the client, tenders offer the greatest value for the amount of money spent. This is due to the fact that the client can choose from a wide pool of potential suppliers to select the ones that can produce the highest quality product or service at the lowest price point. This allows the company, establishment or organization to save money without having to compromise on quality. Therefore, despite being quite time consuming, tendering is, in my opinion, a profitable long-term process from an organization’s point of view.

Encourages Competition: The process of tendering helps promote a competitive market. This is because a number of potential contractors, firms or suppliers get a chance to bid for every project. And because selection depends on quality and price, every bidder tries to reduce operational inefficiencies and redundancies as much as possible in order to lower expenses and improve quality. This entire process encourages healthy competition in the market and prevents complacency and laziness, which in turn provides a boost to innovation and new ideas.

Easier Entry: The system of tendering makes it easier and simpler for new firms to enter the market or even a particular industry. This is due to the fact that contracts under this system are awarded on the basis of predetermined, objective criteria. As a result, even a firm that is a new entrant to the market, having no connections or contacts in the industry, can win a prestigious and lucrative contract by providing the highest value for the client’s money. This process therefore helps new firms to quickly get a foothold in the market or industry, thus significantly lowering the traditional barriers to entry.

Liquidated damages are pre-agreed fixed sums payable for specific breaches, such as late delivery.

Clauses 1 and 3 meet this definition.

Clause 2 is uncertain (“to be agreed”) and unenforceable; clause 4 is a warranty, not LDs.

The question explicitly mentions labour standards and ESG (environmental, social, governance).

Modern Slavery (C): relates directly to labour and human rights (forced labour, trafficking, child labour).

Sustainability (D): covers environmental and social impacts, resource use, and long-term responsibility, key under ESG.

Indemnity and warranty are general legal/contractual concepts, and ISO9000 is a quality management standard, not specifically focused on labour/ESG.

Price adjustment formulae are typically tied to objective, external indices such as fuel prices, labour rates, or commodity costs. Rising fuel costs directly affect logistics and production expenses and are a legitimate reason to activate such clauses.

A previously used specification must always be robustly challenged to see how well it fits the proposed circumstances. Aspects which appear not to fit should be analysed to understand why they were included in the sample specification and whether this changes the view on whether or not they should be omitted or changed.

Contract schedules (or appendices) are part of the legally binding agreement and usually contain supporting or detailed information that complements the main clauses — for example, policies, commitments, and technical details.

Health and safety commitments (B): These are operational requirements that demonstrate compliance with legislation and are typically annexed as schedules.

Non-disclosure agreement (D): Confidentiality obligations or NDAs are often attached as schedules or referenced documents.

Financial statements, supplier references, and blank RFQ forms are pre-contract due diligence or sourcing documents and do not form part of the contract schedules.

Liquidated damages are a pre-agreed amount stated in the contract, payable upon a specific breach. These clauses are enforceable if the amount is a genuine pre-estimate of loss and not punitive. In this case, the £5 per tyre is a typical liquidated damages clause as it quantifies the penalty for non-compliance.

Liquidated damages (LDs) are pre-agreed sums payable for specific breaches (commonly late delivery), intended as a genuine pre-estimate of loss.

Clause 1: £1,000 per server per day for late delivery → clear pre-agreed daily amount = LD.

Clause 3: £40,000 per day up to 50% of contract price → again, defined LD structure.

Clause 2: “Amount to be agreed” is uncertain and not a valid LD amount.

Clause 4: A full refund after five years for performance degradation is more like a warranty / guarantee, not a liquidated damages clause.

Thus, LD examples are 1 and 3 only → option C.

Specifying that suppliers hold certification to standards like ISO 14001 offers assurance that they adhere to recognised environmental management practices, promoting consistency and reliability. Such standards are internationally recognised, facilitating understanding among both local and global bidders. However, certification does not guarantee the exclusion of all polluting suppliers, nor does it eliminate the need for internal environmental training within the purchasing organisation.

- A call off or a term contract is one which exists for a fixed period of time, rather than for a specific purpose

- A formal framework agreement does have some legal standing but it is not a contract, primarily because there is no consideration involved, but it is an overarching (or umbrella) agreementunder which contracts can be created (this holds true in English law but may not be right in other jurisdiction)

- A framework arrangement is a rather loose set-up, without any legal standing. It usually occurs when an organisation has decided for itself to limit the number of suppliers it is willing to work with and, through a purely internal process, sets up an approved list of such suppliers.

- A performance management framework including KPIs and targets, the assessment scheme and incentives, disincentives, bonuses and penalties. It is a schedule to a contract and only legally binding if it is referred from contract clauses.

Incentivised pricing is designed to motivate suppliers to meet or exceed performance targets by providing financial or other incentives. In urgent projects, such as constructing a hospital ward during a pandemic, incentivised pricing encourages suppliers to accelerate delivery without compromising on quality. This supports the buyer’s need for speed and reliability.

A simple definition of consideration is as follows – an exchange between the parties which results in a benefit to one party, and a detriment to the other. The case of Currie v Misa (1874) LR 10 Ex 153 provides an apt description of this:

“A valuable consideration, in the sense of the law, may consist either in some right, interest, profit, or benefit accruing to the one party, or some forbearance, detriment, loss, or responsibility, given, suffered, or undertaken by the other.”

A practical example of this can be found by examining a simple contract. Party A offers £500 to Party B, who in exchange will fit his car with a new engine. Party A receives the benefit of his car being fixed, whilst Party B incurs the detriment of having to take time, effort, and perhaps expenses to fix the car.

Liquidated damages are presented in certain legal contracts as an estimate of otherwise intangible or hard-to-define losses to one of the parties. It is a provision that allows for the payment of a specified sum should one of the parties be in breach of contract.

Understanding Liquidated Damages

Liquidated damages are meant as a fair representation of losses in situations where actual damages are difficult to ascertain. In general, liquidated damages are meant to be fair, rather than punitive.

Liquidated damages may be referred to in a specific contract clause to cover circumstances where a party faces a loss from assets that do not have a direct monetary correlation. For example, if a party in a contract were to leak supply chain pricing information that is vital to a business, this could fall under liquidated damages.

A common example is a design phase for a new product that may involve consultation with outside suppliers and consultants in addition to a company ' s employees. The underlying plans or designs for a product might not have a set market value. This may be true even if the subsequent product is crucial to the progress and growth of a company. These plans may be deemed to be trade secrets of the business and highly sensitive. If the plans were exposed by a disgruntled employee or supplier, it could greatly hamper the ability to generate revenue from the release of that product. A company would have to make an estimation in advance of what such losses could cost in order to include this in a liquidated damages clause of a contract.

Limitations of Liquidated Damages

It is possible that a liquidated damages clause might not be enforced by the courts. This can occur if the monetary amount of liquidated damages cited in the clause is extraordinarily disproportional to the scope of what was affected by the breached contract.

Such limitations prevent a plaintiff from attempting to claim an unsubstantiated exorbitant amount from a defendant. For instance, a plaintiff might not be able to claim liquidated damages that amount to multiples of its gross revenue if the breach only affected a specific portion of its operations. The concept of liquidated damages is framed around compensation related to some harm and injury to the party rather than a fine imposed on the defendant.

The courts typically require that the parties involved make the most reasonable assessment possible for the liquidated damages clause at the time the contract is signed. This can provide a sense of understanding and reassurance of what is at stake if that aspect of the contract is breached. A liquidated damages clause can also give the parties involved a basis to negotiate from for an out-of-court settlement.

Liquidated damages are an amount of money, agreed upon by the parties at the time of the contract signing, that establishes the damages that can be recovered in the event a party breaches the contract. The amount is supposed to reflect the best estimate of actual damages when theparties sign the contract. These usually apply to a specific type of breach, and in construction, it is frequently the failure to complete work on time.

Liquidated damages clauses are usually written as some sort of formula, for example:

Total Contract Price – [(X amount of $ per day) x (number of days late)]

Including a liquidated damages clause can provide many benefits, the most important of which ispredictability. When setting a predetermined amount of damages, it allows both parties a chance to negotiate and settle on a number they both feel is fair and reasonable.

From the owner’s perspective, this acts like a cheap form of insurance against your contractors. In the event of a breach, the owner can immediately calculate the damages without going through the trouble of proving actual damages. Proving actual damages can be a complicated, lengthy, and costly process.

From a contractor perspective, this allows them to analyze the level of risk involved, and schedule appropriately. It also allows them the opportunity to limit the damage claims of the owner.

One of the advantages of using the RFQ method to procure pricing is that the company making the solicitation does not need to prepare any documentation, as requests are sent out privately. With less paperwork to prepare, turnaround times for quotes are reduced. Administration cost is also lower in compare with other procurement method like ITT or RFP. RFQ is usually used in low value purchase, where buyer knows the detailed specification and the price is the only variable that need to consider.

To use RFQ effectively, the buyer should attach the detailed specification and standard terms & conditions. The RFQ should only be sent to verified suppliers.

In certain circumstances, where two parties have monetary debts against each other, the right to set-off may arise. A right of set-off allows a (“Party 1”) to take into account the amount owed to it by the second party (“Party 2”) against any amount owed by Party 1 to Party 2, each party must be a debtor and a creditor.

Common law provides the key features that must be present for set-off to arise are;

1. mutuality of debts (each party must be the sole beneficial owner of the debt it is owed and the sole person liable for the debt it owes)

2. the claims each party has must be for non-payment of money

The common law provisions of set-off can be greatly enhanced by the inclusion of a contractual right to set-off (this is discussed further below) so that set-off is applicable in a greater range of situations. If you envisage set-off being a useful right it is not advisable to rely on the implied ability to use it (via common law or equitable set-off). Common law and equitable set-off are subject to various conditions and limitation however, a contractual right of set-off can be drafted to ensure parties are able to agree exactly how and when set-off should be applied.

In the above scenario, the supplier owes the manufacturer the payment for damages, while the manufacturer owes the supplier the payment for goods. This is mutuality of debts, which leads to right of set off.

One-off purchases are ideal for unique, non-recurring needs such as equipment for a special project. These purchases are typically not repeated, do not require long-term supplier relationships, and are handled separately from strategic or ongoing procurement activities.

Reasons for including social and environmental criteria may include the following:

- Expected Cost Savings and Financial Motives

- Management Support and Commitment

- Employees

- Altruistic Values

- Power Imbalances along the supply chain

- Image and Reputation

- Government Regulations

- Customers

- Competitors

Management, employees, government, customers and competitors are among the stakeholders that make pressures to the organisation on social and environmental criteria.

Regarding rule of offer and acceptance, there are some differences among legal system around the world. For example, mailbox rule is generally applied in common law countries such as UK, US, Australia,.. while it is ignored in civil law countries. To clarify on rule of offer and acceptance in international trade, offerors may use expressed terms in their offers. These terms known as deemed receipt protocol.

In the early stages of procurement planning, informal methods like networking at trade events are effective for gaining insights without disclosing sensitive procurement intentions. It allows the buyer to explore the market, understand new technologies or suppliers, and develop informed specifications while preserving confidentiality.

Risk-minimising contract terms for outsourcing typically include:

Confidentiality (1) – protects sensitive information.

Variation and price adjustment (4) – allows controlled changes to scope and pricing over time.

Service duration is important but not itself a risk-control clause; employee holiday length is an HR detail, not a key risk term.

Correct answer: 1 and 4 only.

- Strict liability, sometimes called absolute liability, is the legal responsibility for damages, or injury, even if the person found strictly liable was not at fault or negligent. Strict liability has been applied to certain activities in tort, such as holding an employer absolutely liable for the torts of her employees, but today it is most commonly associated with defectively manufactured products. In addition, for reasons of public policy, certain activities may be conducted only if the person conducting them is willing to insure others against the harm that results from the risks the activities create.

- Current liabilities are a company ' s short-term financial obligations that are due within one year or within a normal operating cycle.

- Non-current liabilities, also called long-term liabilities or long-term debts, are long-term financial obligations listed on a company’s balance sheet

- Contingent liability is a potential liability that may occur, depending on the outcome of an uncertain future event.

An insurance policy transfers a specific set of risks such as the fire and flood risk for a particular asset.

The legal liability does not transfer to the insurance company (known as insurer).

Developing and using generic specifications is as import in the sustainable procurement process as it is in the traditional procurement process. During this stage, human/labour rights and environmental performance criteria should be translated into specifications that meet specific requirements of the specified outcome, desired by the procurement action.

The specification stage is key to all types of contract. Building in environmental and social considerations at this early stage, provides a clear indication to suppliers that sustainability is important to the UN organization. Consider available alternatives which are less environmentally and socially damaging. Consider all the phases of a product’s life cycle (e.g. production, transportation, maintenance, disposal, etc) when determining its cost and environmental impact. Assess the overall environmental and social integrity of suppliers by looking at their policies and practices.

Specifications which are output-based rather than input-based can increase supplier innovation, reduce waste and minimise harmful social and environmental impacts.

Referencing recognised international standards like ISO 27001 in specifications ensures that all potential suppliers understand and meet a uniform set of expectations regarding data security. This not only promotes consistency but also reduces the burden on the buyer to evaluate varied, incompatible approaches.

A cost reimbursable contract (sometimes called a cost plus contract) is one in which the contractor is reimbursed the actual costs they incur in carrying out the works, plus an additional fee. Option Eof the NEC3 Engineering and Construction Contract (ECC) is an example of a cost reimbursable contract.

Model forms of contract are published by some industry or professional organisations such as FIDIC, ITC, CIPS,... These forms are often carefully prepared by legal professionals, with correct legal terminology. The standard clauses within these forms are based on fair and balanced risk/reward allocation between the contracting parties. The model contract forms also include standard clauses to be selected or deleted on an as required basis.

Despite being standardised to be used in any jurisdiction, legal advice may be required if the users decide to make variations to the forms.

The correct answer should be " Model contract form ' s standard clauses often contain correct legal terminology without recourse to third party experts. "

Express terms are those specifically stated in writing or verbally agreed in the contract:

Retention of title term (A) – typically clearly written in the contract.

Liquidated damages term (C) – also explicitly written and agreed.

By contrast:

Terms inserted by the Sale of Goods Act, business efficacy test, or custom of the trade are implied terms, not express.

SLAs define service levels and performance detail such as:

Frequency of service (1)

Staff qualifications (3)

Stockholding requirements (4)Dispute procedures (2) belong in the contract, not the SLA.

" Shall " denotes a mandatory requirement in contract language and implies absolute obligation. Unlike " reasonable endeavours " or " best endeavours " , which indicate a duty to try, " shall " creates a strict, enforceable duty to perform the task specified.

A framework agreement is an agreement with one or more suppliers/providers which sets out terms and conditions under which individual contracts (call-offs) can be made throughout the term of the agreement.

A framework agreement itself is not a contract, but the call-offs made from it are.

Framework arrangements create a streamlined and flexible process for procuring goods, works or services

Where a framework for the same goods, works or services is awarded to several suppliers, there are three possible options for awarding call-off contracts: direct award (or direct call-off), mini-competition or a combination of both.

Option 1 – Apply the terms of the framework agreement (direct award).

Where your requirements match the terms and/or specification of the framework agreement (in the event of any query, you should clarify the situation with the organisation that established the framework), a particular call-off should be awarded without re-opening competition. The call-off should be awarded to the provider who is identified as the most economically advantageous tender based on the award criteria used at the time that the framework was established (i.e. the supplier ranked no. 1). Randomly selecting a supplier off a framework is not permitted.

Option 2 – Hold a mini-competition between capable suppliers.

If your requirements do not match the terms and/or the specification of the framework, you should conduct a mini-competition exercise. Whilst it is not permitted to substantially change the basic terms or specification of the framework, in running a mini-competition it is possible to supplement or refine the basic terms of the framework prior to making a call-off. Examples of such terms are:

- The particular goods/services/works required;

- Particular delivery timescales;

- Particular invoicing arrangements and payment profiles;

- Associated services such as installation, maintenance and training;

- Quantity;

- Functional specification.

Under no circumstances should brand names or brand-specific descriptions of goods be used e.g. BIC Biro Pen, Hewlett-Packard Printer, Dell computer. Descriptions should give reference to the characteristics and outputs of the product or service. Where no other description is possible, any reference should be qualified by adding the words ‘or equivalent’.

When a mini-competition exercise is held, all suppliers appointed to the framework that are capableof meeting the requirement must be invited to submit a tender. (This might just relate to suppliers within a particular ‘lot’). You must not limit the mini-competition exercise to selected providers. A time limit for submitting the tender must be set and advised to competing suppliers. This time limit must be reasonable, taking account of the complexity of the requirement.

The call-off must be awarded on the basis of the framework award criteria and new criteria cannot be added, although, where permitted, the weightings may be varied to take account of a particular requirement. However, in adjusting the weightings, care must be taken to ensure that any such changes do not have an adverse effect on competition.

Option 3 - Combination of direct award and mini-competition

To use a combination approach, the procurement documents must state that this route may be used. The procurement documents will also specify which terms may be subject to the re-opening of competition.

Request for quotations is often used when the only variable is price and the purchase value is under a financial threshold. This process is less formal than ITT. RFQ should be used in the following circumstances:

- Low-value, low-risk purchases

- When the specifications are sufficiently defined or the product/service is standardised

- Where the suppliers are pre-qualified

- Where there is a framework agreement which specifies the contract terms and conditions.

Without further explanation, a schedule may be deemed to form an integral part of the obligations of either or both parties. Obviously, the scope or binding nature of such schedule depends on the way it is referred to in the obligatory language of the main agreement. Accordingly, merely attaching the general terms and conditions of sale without explaining to which part of the sale they apply or which provisions apply does not subject a sale pursuant to the body text of the agreement to those general terms and conditions.

Subcontracting is the practice of assigning, or outsourcing, part of the obligations and tasks under a contract to another party known as a subcontractor.

The ITT is issued by the buyer and typically includes:

Requirements, scope, and delivery milestones (C).

Evaluation criteria, instructions to tenderers, contract conditions, etc.

Supplier rates and liquidity ratios belong in the supplier response or financial evaluation. BAFO is a later negotiation step, not content of the ITT itself.

The five essential elements of a valid contract are: offer, acceptance, consideration (something of value exchanged), capacity (legal ability to contract), and correct form (in writing if required). These ensure that contracts are legally enforceable and binding.

Risk-minimising clauses typically include:

Confidentiality clauses (1) to protect business data.

Variation and price adjustment clauses (4) to allow flexibility for scope or cost changes.Service duration and holidays are administrative and not risk-control terms.

KPIs and the targets for supplier should be SMART:

- Specific: What exactly do you want to achieve?

- Measurable: How will you identify that you have achieved your goal?

- Achievable: Is your goal really attainable?

- Relevant: Is it relevant to you or, in other words, does it align with where you want to be?

- Time-bound (or timely): When will you deliver your goal, and what are the key milestones?

The two KPIs (Delivery in one hour, Return orders in one hour) are not realistic and achievable for international suppliers. Therefore, you should not put such high targets for supplier.

A service-level agreement (SLA) is a commitment between a service provider and a client. Particular aspects of the service – quality, availability, responsibilities – are agreed between the service provider and the service user. The most common component of an SLA is that the services should be provided to the customer as agreed upon in the contract.

A customer service charter is a document that outlines how an organization promises to work with its customers along with providing insights into how an organization operates.

A service guarantee is a marketing tool service firms have increasingly been using to reduce consumer risk perceptions, signal quality, differentiate a service offering, and to institutionalize and professionalize their internal management of customer complaint and service recovery.

Gainshare is an incentive for cost control

Liquidated damage is common type of disincentive for late completion

Service credit is a remedy for not achieving targets set out in an SLA

Fixed bonus payment is an incentive for early completion

A revocation of offer is the withdrawal of a previous offer to engage in some sort of legally binding contract. The previous offer had to have been such that it would have immediately become legally binding if the other party had formally agreed to it.

A core ruling defining revocation of offers was established by Payne v. Cave. This case established that neither party is bound to an agreement until an offer has been made by one and formally accepted by the other.

If an offer has been made, the offering party has a right to withdraw it up to formal acceptance by the offeree. Revocation basically serves as formal, legally verifiable notice that a withdrawal was made, and it ' s valid so long as it is communicated to the offeree before they accept.

The case of Byrne v. Van Tienhoven supports this by establishing that the withdrawal of an offer by telegram is only valid if the telegram is received before the offer is accepted. The case of Dickinson v. Dodds further establishes that the party making the offer can communicate the revocation through a third party.

A price adjustment clause, also known as a price variation or indexation clause, provides a structured method for managing potential changes in price over the contract ' s duration. This clause ensures that any price increase must be based on predefined and agreed-upon criteria, such as inflation rates or cost indices. This prevents arbitrary or unexpected price increases from the supplier.

Capacity means the legal ability to form a contract. A party lacks capacity if they are:

Of unsound mind or mental incapacity (1), or

A company acting beyond its powers (ultra vires) (4).

A failure to concentrate or being 19 years old does not affect legal capacity.

A well-drafted service specification includes a clear description of the services to be delivered, fault rectification timelines, and the duration of service. These define scope, performance expectations, and timelines. Evaluation methodology and contract terms are important, but they are part of separate procurement or contractual documentation.

When parties do not negotiate face-to-face, a key QUESTION NO: becomes when things like acceptances, rejections and revocations take effect. The general rule is that acceptances are effective on dispatch (when they are mailed). Everything else becomes effective when the offeror actually receives them. This idea is codified by the “mailbox rule” which states that acceptance is effective on dispatch, even before the offeror has received it. (The one minor exception to this rule involves option contracts for which acceptances are not effective until they are received by the offeror.)

IMechE/IET: Institution of Mechanical Engineers/Institution of Engineering and Technology - two separate institutes that issue jointly agreed model forms covering the design, supply and installation of electrical, electronic and mechanical plant including special conditions for the ancillary development of software. Car lifts are mechanical products, so IMechE/IET is the most suitable model contract for this type of product.

FIDIC is a French language acronym for Fédération Internationale Des Ingénieurs-Conseils, which means the international federation of consulting engineers. It was started in 1913 by the trio of France, Belgium and Switzerland. The United Kingdom joined the Federation in 1949. FIDIC is headquartered in Switzerland and now boasts of membership from over 60 different countries. FIDIC published its first contract, titled The Form of contract for works of Civil Engineering construction, in 1957. As the title indicated, this first contract was aimed at the Civil Engineering sector and it soon became known for the colour of its cover, and thus, The Red Book. It has become the tradition that FIDIC contracts are known in popular parlance by the colour of their cover. This first contract by FIDIC was undertaken jointly with the International federation of Building and Public works. FIDIC’s concerted effort at achieving broad consultation and acceptance of its contract forms has seen subsequent editions of its contracts being ratified by the International Federation of Asian and Western Pacific Contractors Association, Associated General Contractors of America and the Inter-American Federation of the Construction Industry, Multilateral Development Banks among others. Because of the broad support it enjoys, FIDIC contracts are the foremost contracts in international construction.

The Chartered Institute of Procurement and Supply (CIPS) has some model contracts for IT functions including: supply and installation of computer equipment, support and maintenance of bespoke software, servicing of computer equipment,...

The International Trade Centre (ITC) produces contracts specifically designed for small companies doing international business, covering the sale of goods, distribution, services and joint ventures.

Creating a detailed specification and publicly advertising the requirement are key preparatory steps in issuing an ITT (Invitation to Tender). These ensure that suppliers understand the requirement and have the opportunity to respond, promoting transparency and competition.

Price escalation clauses allow suppliers to raise prices during the contract term, potentially undermining budget control. Exclusion clauses limit or remove the supplier ' s liability, which could leave the buyer unprotected in case of breach or defects. These clauses present clear risks and require careful review or negotiation.

Contracting on the supplier’s terms can pose risks for the buyer. Common disadvantages include retention of title clauses (C), where the supplier retains ownership of goods until full payment is made. Also, suppliers may include clauses allowing them to raise prices without notification (E). These terms shift risk to the buyer and reduce predictability and control.

FIDIC is the International Federation of Consulting Engineers (or Fédération Internationale des Ingénieurs Conseils in French). FIDIC has produced many publications, including the model form contracts, best practice guidances, research on sustainability, integrity and risk management. FIDIC model form contracts have been developed by this organisation since 1999, now they consist of several different books which are marked by colours. Thus, FIDIC model contracts also have the nickname " Rainbow suite of contracts " . Basically, the " Rainbow Suite " include the following books:

* Yellow book: Plant and Design-Build Contract (2 editions: 1999 and 2017)

* Silver book: EPC/Turnkey Contract (2 editions: 1999 and 2017)

* Red book: Construction Contracts (2 editions: 1999 and 2017)

* Emerald book: Conditions of Contract for Underground Works (1st Ed 2019)

* Gold book: Design, Build and Operate Contract Guide

* Pink book: Construction Contract Multilateral Development Bank Harmonised Ed (2 editions: 2005 and 2010)

This type of model contract is commonly used around the world because its author, International Federation of Consulting Engineers, collaborates closely with development banks such as World Bank, Africa Development Bank, Asia Development Bank, etc. Every construction project that is financed by these institutions must adopt the FIDIC contracts.

ITC and leading legal experts developed eight generic contract templates that incorporate internationally recognized standards and laws for most small business situations.

CIPS has several model forms of contract designed specifically for IT buying and servicing.

A Retention of Title clause allows the seller to retain ownership of goods until full payment is received. If included in a contract, this clause would have enabled ACC to claim ownership of the number plates and potentially recover them from Elite Motors Ltd, even in administration. It protects suppliers against buyer insolvency.
