Councils may compel the attendance of witnesses and the production of books, papers or other evidence at any meeting of the council or any committee of the council and for that purpose may issue subpoenas, signed by the president of council or the chair of the committee, which shall be served in any part of this Commonwealth. If a witness refuses to testify to any fact within the witness's knowledge or to produce any books or papers in the witness's possession or control required to be used as evidence in any case, the borough solicitor shall report the facts relating to the refusal to the court of common pleas. If the court determines the evidence required of the witness to be legal and competent, it shall order the witness to testify or produce the evidence required.
