Acting Prime Minister
An Acting Prime Minister will be standing-in for the incumbent (not assume office), acting in the Prime Minister's office, temporarily, and if a designated minister was allocated in advance, automatically, all while the incumbent is in office. However, any Acting Prime Minister will not assume office, automatically (as Interim Prime Minister), after 100 consecutive days, when the Prime Minister, legally, is deemed to be "permanently incapacitated", since the "100 consecutive days" was set by law as a limit, not a delegated authority, inasmuch limit for the incumbent to be temporarily incapacitated in office and a limit for the Acting Prime Minister to act in the Incumbent's office.
