A saving clause is a legal provision that exempts specific instances from the effect of a law or a contract. There are several synonyms for the term, including a safety clause, an exception clause, a non-obstante clause, and a non-derogation clause. A safety clause is often used in contracts to provide a safety net that protects all parties from unintended consequences of the agreement. An exception clause is similar in nature, providing an exception to an otherwise applicable law or provision. A non-obstante clause is commonly used in legal instruments to negate the effect of a law or provision. Lastly, a non-derogation clause ensures that a person or entity's rights are not weakened or diminished by other legal agreements.
