The Interpreter Who Explains the Culture Is a Liability

A witness keeps looking down, avoids the judge’s eyes, and answers “yes” to almost everything. The interpreter has a strong hunch: in this witness’s culture, holding eye contact with an authority figure can read as disrespect, and agreeable answers can be a form of deference. So the interpreter leans toward the bench and explains that. Helpful, right?

It is one of the most damaging things an interpreter can do.

Render the Behavior, Do Not Diagnose It

California Rule of Court 2.890 requires interpreters to render a complete and accurate interpretation and to remain impartial throughout the proceeding. Offering the court an explanation of a witness’s cultural behavior violates both requirements at once. It adds something that was not in the source, and it puts the interpreter’s own assessment into the record in place of neutral rendering.

The interpreter who “explains the culture” has also quietly appointed themselves an expert witness nobody retained, without an oath, without cross-examination, and without knowing the answer. Whatever general knowledge the interpreter has about cultural norms says nothing about why this particular witness is behaving this way. It might be cultural. It might be fear, confusion, fatigue, or something specific to this person that no general rule explains. The moment the interpreter offers a reason, they have traded a fact for a guess and presented that guess as expertise.

An interpreter’s job is to convey what is said and let the court see what is done. If a witness’s demeanor raises a question, the judge and the attorneys can explore it directly with the witness, exactly as they would with an English speaker. The same restraint applies to comprehension: it is not the interpreter’s role to decide whether the witness understood a question based on the answer. Deciding what the witness “really meant” or “must have understood” is not neutrality. It is advocacy in a quiet voice.

Neutrality Includes How It Looks

Real neutrality is stricter than most people expect, because it covers appearances, not only intentions. An interpreter can be perfectly impartial and still create a problem by looking partial.

Picture the interpreter chatting warmly with one side’s attorneys in the hallway, then walking in to interpret. The interpreter may have worked with that firm for years, and there may be nothing improper about it at all. But a jury that does not know the history sees the interpreter appearing friendly with one side. That perception alone can undercut the neutrality the interpreter is supposed to embody. It is why professional interpreters keep a certain formality in the building, avoid social conversation in the room, and position themselves to be heard without becoming part of the scene. They are not being cold. They are protecting the appearance of impartiality, which is part of the job.

The Interpreter Is a Conduit, Not a Commentator

All of this comes back to one line. The interpreter is there to give the non-English speaker the same footing an English speaker would have, and no more. An English speaker does not come with a narrator explaining their culture to the judge, deciding whether they understood the question, or vouching for what they meant. Adding those things for a non-English speaker is not leveling the field. It is tilting it, and it is tilting it based on the interpreter’s assumptions.

This is also why a well-meaning bilingual friend or relative is the wrong choice for a legal setting, even setting aside their stake in the outcome. They will explain. They will smooth. They will answer the “what he means is” question because it feels like helping. A trained interpreter knows that every one of those moves corrupts the very record they were brought in to protect.

What Good Looks Like

• The interpreter renders what the witness says and lets the witness’s demeanor speak for itself.
• Questions about culture, motive, or comprehension go to the witness through counsel, not from the interpreter to the bench.
• The interpreter keeps a professional distance from both sides, including in the hallway.
• If a genuine language issue needs flagging, the interpreter flags it plainly and briefly, on the record, without editorializing.

The Bottom Line

You want a conduit, not a commentator. An interpreter who explains a witness’s culture, decides what they understood, or vouches for what they meant is not adding value. They are adding their own untested judgment to your record and creating an appearance problem while they do it. The interpreter who renders faithfully and stays out of the way is the one keeping your proceeding clean.
