The Legislature shall provide by law for the establishment of a Board of Parole and the qualifications of its members. Said board, or a majority thereof, shall have power to grant paroles after conviction and judgment, under such conditions as may be prescribed by law, for any offenses committed against the criminal laws of this state except treason and cases of impeachment. The Governor, Attorney General and Secretary of State, sitting as a board, shall have power to remit fines and forfeitures and to grant respites, reprieves, pardons, or commutations in all cases of conviction for offenses against the laws of the state, except treason and cases of impeachment. The Board of Parole may advise the Governor, Attorney General and Secretary of State on the merits of any application for remission, respite, reprieve, pardon or commutation but such advice shall not be binding on them. The Governor shall have power to suspend the execution of the sentence imposed for treason until the case can be reported to the Legislature at its next session, when the Legislature shall either grant a pardon, or commute the sentence or direct the execution, or grant a further reprieve.
