It is always presumed than an acting or interim official has all of the powers and prerogatives of the office they (temporarily) assume. Thus we have had interim presidents nominate game moderators and members of the Supreme Court, acting senators vote on and introduce legislation, and acting governors sign bills into law.
The chancellor, who must be a member of the Council, shall have the power [. . .] to administer the functions of the head of state as acting governor upon the death, impeachment, recall, or resignation of the governor, or whenever he should otherwise become unable to execute the duties of his office.
"The functions of the head of state" necessarily includes all powers vested in the governor by law, in absence of a statement to the contrary in the constitution itself.
