A subpoena is a court order that compels an individual to provide testimony or produce documents relevant to a legal proceeding. It is a powerful tool that can be used to gather evidence and information in both civil and criminal cases.
There are a number of reasons why someone might want to avoid a subpoena. For example, they may not want to testify about sensitive or embarrassing information, or they may not want to produce documents that could be used against them in court.
