Which expression means to take legal action without affecting any previously existing rights?

The expression "without prejudice" refers to a legal term that allows a party to take legal action or make a statement without compromising or affecting any pre-existing rights or claims. This term is often used in legal contexts, particularly during negotiations or discussions, to ensure that any settlements or admissions made in the course of discussions do not have an impact on the parties' legal rights should the matter proceed to court.

When something is done "without prejudice," it indicates that the action or statement cannot be used against the party in any future proceedings, preserving their ability to assert their original rights. Therefore, this term effectively protects interests while allowing for open dialogue and alternative resolutions.

The other options have different meanings. "Not prejudicial" typically refers to something that does not disadvantage someone in legal terms but does not directly address the preservation of rights. "Without waiver" suggests that a party is not giving up any rights but does not encompass the full implication of being able to take action without affecting existing rights. "Not binding" means that an agreement or statement does not create a legal obligation, which is not specifically related to existing rights or claims.
