Israeli Prime Minister Benjamin Netanyahu was discharged from the hospital Monday after being fitted with a pacemaker earlier.

His release comes ahead of the first ratification vote in a controversial judicial overhaul sought by his religious-nationalist coalition.

A Reuters witness saw Netanyahu's convoy depart Sheba Medical Center near Tel Aviv, which admitted him late Saturday and fitted him with a pacemaker after doctors said a heart monitor had detected "temporary arrhythmia."

Netanyahu's office and Sheba said he had been discharged.

On Monday, the Knesset is due to hold final readings of a bill amending a law enabling the Supreme Court to void decisions made by the government and ministers it deems "unreasonable."

If passed – a likelihood given Netanyahu's parliamentary majority – the bill would be the first of a package of reforms the prime minister is pursuing in the name of balancing out branches of government, but which his critics see as curbing judicial independence.
