Section 6

The governor shall have power to grant reprieves, commutations and pardons, after conviction, for all offenses, except treason and cases of impeachment, upon such conditions and with such restrictions and limitations as he may think proper, subject to such regulations as may be provided by law relative to the manner of applying for pardons. Upon conviction for treason he shall have the power to suspend the execution of the sentence until the case shall be reported to the legislature at its next meeting, when the legislature shall either pardon, or commute the sentence, direct the execution of the sentence, or grant a further reprieve. He shall annually communicate to the legislature each case of reprieve, commutation or pardon granted, stating the name of the convict, the crime of which he was convicted, the sentence and its date, and the date of the commutation, pardon or reprieve, with his reasons for granting the same.
