Any member of the board shall have the right to administer oaths to witnesses.
No action to suspend, revoke or cancel any certificate shall be taken by the board until the accused or his counsel has been furnished with a statement of the charges against him, or it, and a notice of the time and place of hearing thereof; the furnishing of the charges and such notice to be given said accused at least fifteen days prior to the date of hearing.

The bringing of such a petition within such period shall operate to continue the registration in full force and effect pending the decision of the court. After such notice to the board as the court deems necessary, it shall review such action, hear the witnesses, and shall affirm the decision of the board unless it shall appear that it was made without proper cause or in bad faith, in which case the decision of the board shall be reversed. The court shall hear such petition within thirty days after the bringing thereof. The appeal from the decision of the board provided by this section is in the alternative to that provided by section sixty-four, and a decision of the court upon a petition brought under this section shall be final and conclusive.
