Relating to testimony or the production of evidence before a house of the legislature or a legislative committee.

SB 1386 removes a witness's right to refuse testifying before Texas legislative committees or houses of the legislature on the grounds that testimony might "disgrace" them or make them "infamous." It requires witnesses to testify or produce evidence even if they claim it could incriminate them, but protects them from criminal prosecution (except for perjury) using compelled testimony. The bill also guarantees witnesses the right to have legal counsel present during testimony. This directly affects individuals called to testify before Texas legislative committees or state legislative bodies.
