unchangeable contract

[/ˌʌnˈtʃeɪndʒəbəl ˈkɒntrækt/]
nounpl: unchangeable contracts
contrato imutável
1. A legal agreement between two or more parties that cannot be modified, altered, or terminated without the consent of all parties involved, or that is legally binding with no provisions for changes
The unchangeable contract locked both companies into their original terms for ten years.
O contrato imutável vinculou ambas as empresas aos termos originais por dez anos.
2. In legal contexts, a contract whose terms are fixed by law or judicial decree and cannot be unilaterally changed
Once the court approved the unchangeable contract, neither party could request modifications.
Depois que o tribunal aprovou o contrato imutável, nenhuma das partes poderia solicitar modificações.
In Brazil, unchangeable contracts are often subject to consumer protection laws (Código de Defesa do Consumidor), which may override strict contractual immutability to protect consumers. In the US, such contracts are more common in commercial agreements between sophisticated parties. The concept reflects different legal philosophies: Brazilian law emphasizes equity and consumer protection, while US contract law emphasizes freedom of contract and party autonomy.
