It is unlawful for any employer in Massachusetts, with respect to any of its employees or prospective employees — including any person applying for employment as a police officer — to subject such person to, or request such person to take, a lie detector test, or to discharge, not hire, demote or otherwise discriminate against such person for the assertion of rights arising under this law. This prohibition shall not apply to lie detector tests administered by law enforcement agencies as otherwise permitted in criminal investigations.
