In every case where a State board or commission is authorized by statute to appoint the executive head of a State agency or institution, that board or commission may appoint an acting executive head of that agency or institution to serve
An acting executive head of a State agency or institution appointed in accordance with this section may perform any act and exercise any power which a regularly selected holder of such office could lawfully perform and exercise. All powers granted to an acting executive head of a State agency or institution under this section shall expire immediately
Each State board or commission may determine (after such inquiry as it deems appropriate) that the executive head of a State agency or institution whom it is authorized by statute to appoint is physically or mentally incapable of performing the duties of his office. Each such board or commission may also determine that such incapacity has terminated.
