Israel’s Supreme Court is poised to overturn the first of Prime Minister Benjamin Netanyahu’s judicial reforms by an 8-7 margin, according to a leaked version of the decision that is set to be handed down formally on January 12.

The reform is a change to one of Israel’s so-called Basic Laws, stripping the judiciary of the ability to overturn legislation or state action on the basis of “reasonableness.” Critics say that the “reasonableness” standard is subjective and allows unelected judges to rule on the basis of their personal views.

Of all the reforms initially sought by Netanyahu’s conservative government, the end of the “reasonableness” standard was the most moderate, and widely accepted. It passed the legislature, or Knesset, on a party-line vote after months of opposition protest.
