Why must an interpreter be sworn before the witness?

An interpreter must be sworn before the witness primarily to ensure the integrity of the translation. This process is crucial because it underscores the interpreter's obligation to provide an accurate and faithful representation of the dialogue or testimony being presented in court. By taking an oath, the interpreter commits to maintaining impartiality, confidentiality, and professionalism, which are essential elements in a legal setting. This responsibility becomes especially important when dealing with legal terminology, nuances, and emotions that can significantly impact the case at hand.

When an interpreter is sworn in, they are legally bound to interpret without bias and to convey only what is being said, thus helping to uphold the rights of the parties involved and ensuring that the legal process is fair and just. The limitations of the other options highlight their lesser relevance in this context; for example, gaining the court's respect or verifying qualifications while important, do not directly address the core obligation to produce a truthful and accurate translation of the proceedings.
