What is the consequence of not serving appropriate witness fees along with a subpoena?

When a subpoena is issued, it is accompanied by the requirement to pay appropriate witness fees as specified by law. This requirement is significant because it serves as an incentive for witnesses to comply with the subpoena and attend the scheduled proceedings. If the witness fees are not provided, the witness has a legal right to refuse to attend, as they are not being compensated for their time and potential travel expenses.

The rationale behind this requirement reflects the broader legal principle that individuals should not be compelled to bear personal costs or inconveniences to attend court as witnesses without compensation. Therefore, the absence of these fees can impact the willingness of a witness to appear, which is why the choice highlighting the witness's right to refuse attendance is the most accurate consequence of failing to serve appropriate witness fees along with the subpoena.
