Contracts are legally binding agreements between two or more parties, outlining the responsibilities, duties, and benefits of each party. Contracts can be modified at any point during the arrangement, provided that all parties consent to the changes. This can be done by adding an addendum, which adds or clarifies terms without replacing the original contract. However, if a contract contains language prohibiting future modifications, changes cannot be made. In the event of a change in the law, the applicable law to a contract throughout its duration is typically the one in force at the time of its signature, although there are exceptions.

Contract modifications and the law
Contract modifications are a common occurrence, and they can happen before or after a contract has been signed. The law permits contract modifications, but there are specific procedures that must be followed to ensure the changes are legally valid and enforceable.
Firstly, it is important to note that all parties to the contract must agree to any modifications. Verbal or written approval outside the contract is not sufficient, and parties must officially amend the agreement within the contract. Minor modifications can be handwritten and signed or initialled by all parties, while major modifications may require a new contract to be drafted.
State laws govern the requirements around contracts, and contract laws vary by state. Therefore, it is essential to consult a contract lawyer to ensure compliance with local laws. Certain amendments, such as those related to the sale of goods, must be in writing according to state laws. Additionally, if a contract was originally oral, but the modification increases the value of the contract, it must be put into writing to be legally valid.
In the context of international or domestic investment contracts between private parties and states, freezing clauses may be incorporated to "freeze" the application of the law in force at the date of the contract's conclusion. This implies that any legislative or regulatory changes enacted after the date of the contract will not apply. However, the enforceability of freezing clauses depends on the jurisdiction, and some states have established legal principles that invalidate them.
In summary, while contract modifications are generally permissible, it is crucial to obtain the consent of all parties, follow the proper procedures, and ensure compliance with the applicable laws to avoid legal consequences and maintain the legality of the contract.

Freezing clauses
A freezing clause, in the context of contracts, refers to a provision that allows for the suspension or preservation of certain terms or conditions outlined in the contract. Freezing clauses can be used in various scenarios and can apply to different aspects of an agreement. Here are some examples of freezing clauses and how they may be implemented:
Labour and Employment Contexts
In labour relations and employment contracts, freezing clauses are often used to maintain specific terms and conditions during bargaining processes. For instance, while negotiations for a new collective bargaining agreement are ongoing, a freezing clause may stipulate that the terms and conditions of the current agreement remain in effect. This means that neither party can alter rates, terms, or privileges outlined in the existing agreement until certain requirements are met or negotiations are concluded. This type of freezing clause helps maintain stability and prevent unilateral changes during bargaining.
Membership and Subscription Services
Seniority and Bargaining Unit Positions
In certain employment contexts, freezing clauses may be used to address issues of seniority and bargaining unit positions. For instance, an employee hired for a position outside the bargaining unit may have their seniority frozen for a specific period, during which they do not accumulate additional seniority. Upon returning to the bargaining unit, their prior accumulated seniority is reinstated. This type of freezing clause helps maintain fairness and consistency in seniority calculations.
Contractual Definition Freeze
In some cases, freezing clauses may be used in contracts involving the manufacturing and delivery of complex products, such as aircraft. A "contractual definition freeze" (CDF) is a provision that establishes a deadline by which the contractual definition of the product, in this case, an aircraft, must be finalized. This includes finalizing any special customer-requested changes or non-catalogue items (SCNs) that need to be incorporated into the manufacturing process to ensure timely delivery. The CDF date is crucial for coordinating the various stages of production and ensuring that the final product meets the specified requirements.
It is important to note that while freezing clauses can provide flexibility and protection in certain situations, they should be carefully considered and drafted to ensure they align with the overall objectives of the contract and the interests of the parties involved. As with any contractual provision, seeking legal advice or consulting with a contract lawyer can help ensure that freezing clauses are appropriately tailored to the specific needs and requirements of the agreement.

State sovereignty
Legal cases have also played a pivotal role in defining state sovereignty. In the United States, the Constitution's Contract Clause prohibits states from enacting laws that impair the obligation of contracts. This clause has been invoked in numerous cases, such as Fletcher v. Peck in 1810, where the Supreme Court interpreted it to protect public and private contracts from state interference. Similarly, the case of United States ex rel. Von Hoffman v. Quincy affirmed that a state's authorization of a municipal corporation to contract and tax cannot be withdrawn until the contract is satisfied, upholding the sovereignty of the state's contractual obligations.
The concept of legislative sovereignty, as proposed by John Austin, suggests that sovereignty is vested in a nation's parliament, which can change laws at its will. However, this idea doesn't align perfectly with the American system, where the Constitution imposes restrictions on the national legislature's power. The Supreme Court's decision in Marbury v. Madison introduced the concept of judicial review, challenging the notion of legislative sovereignty. This led to a system of constitutional sovereignty, where the power to propose and approve constitutional changes is vested in Congress, states, and special conventions.
While state sovereignty is a fundamental principle, it is not absolute. In certain situations, new laws may supersede existing contracts. For example, public order laws that address issues of public policy and serve the public interest can apply immediately to ongoing contracts. Additionally, in exceptional cases, new laws may provide for their immediate application through transitional legal provisions. Nevertheless, the principle of state sovereignty remains a cornerstone of international relations and contractual agreements, ensuring stability and predictability in the legal landscape.

Contract amendments
When amending a contract, the changes must be made with the mutual consent of all parties involved. Verbal agreements should be avoided as they may lead to disputes. Instead, modifications should be made in writing, either directly on the signed legal document or through an amendment document. Minor adjustments may only require an amendment document outlining the changes, while major changes might necessitate drafting a new contract or an amendment and restatement.
It is important to carefully review the original contract before making any modifications, as provisions outlining the process for amendments may already be in place. Contracts may also explicitly list amendments that cannot be made, and these must be adhered to. If a contract contains language prohibiting future modifications, then changes cannot be made. Additionally, if a contract was originally created orally, but the modification increases the value of the contract, the changes must be made in writing to be considered legally valid.
Amendments do not replace the original contract terms but modify specific portions. For example, an amendment might change the price of goods or the date of delivery without altering the entire contract. When making amendments, it is crucial to ensure that the changes do not breach any existing terms or conditions. If the contract is biased towards one party, negotiations can be made to modify the terms to be more favourable for the other party.

Mutual consent
An addendum can be used to add new terms or conditions to a contract or to clarify ambiguous terms. For example, if a contract only provides the name of the city or town where a party will provide services, an addendum might list the exact location with the address. An addendum becomes part of the original contract and is governed by its terms, but it typically does not need to be signed unless the contract specifies this.
It is important to note that verbal agreements are challenging to enforce and may lead to disputes. Even small verbal agreements should be formalized in writing. All parties must sign updated terms to confirm their consent and make the amendments enforceable. If one party modifies the contract without the agreement of the other, the changes are unlikely to be enforceable.
To avoid common mistakes, it is important to properly document changes, obtain signatures from all parties, and not ignore clauses prohibiting specific amendments. If a contract contains any provisions informing the parties on what to do in the event of a modification, they must follow these terms. Laws concerning contracts vary by state, so it may be beneficial to contact a local contract lawyer for guidance.
