Rule 11-604 Interpreter.

If someone needs an interpreter in court, whether it's a witness who doesn't speak English well or someone who is deaf or hard of hearing, that interpreter has to actually be qualified to do the job. They can't just be someone who knows a little bit of the language.

Before the interpreter starts translating, they have to take an oath or make a formal promise. This promise is that they will translate everything accurately and truthfully. This matters because the whole point of testimony is to get accurate information to the judge and jury. If the translation is wrong or misleading, it could change the outcome of the case.

This rule protects everyone involved. It makes sure that people who don't speak English, or who communicate in another way, can still participate fully and fairly in court. It also gives the other side a way to challenge the interpreter if they have concerns about whether that person is truly qualified or trustworthy.
