Israel's Supreme Court began hearing on Thursday, the first in a series of appeals against a judicial overhaul being unfurled by Prime Minister Benjamin Netanyahu and his religious-nationalist coalition, which has set off an unprecedented domestic crisis. A March amendment to a quasi-constitutional "basic law" limited conditions under which a prime minister can be deemed unfit, or incapacitated, and removed from office. The appellants - backed by Netanyahu's own attorney-general - want that voided.
