Israeli law distinguishes the terms "acting prime minister" (מלא מקום ראש הממשלה), filling in for the incumbent prime minister, temporarily, and acting in the incumbent's office, while the incumbent is in office, and an "interim prime minister" in office. Only if the incumbent prime minister becomes "temporarily incapacitated" will the acting prime minister act in the incumbent's office and will be standing in for him for up to 100 consecutive days, while the incumbent is in office. Legally, the "100 consecutive days" limit, in the language of the law, only stipulates that the incumbent then is deemed to be "permanently incapacitated" and that the limited time for an acting prime minister to act in the incumbent's office is over.
