Netanyahu and his allies passed a law last week that removes the high court’s ability to annul government decisions considered “unreasonable.” The “reasonableness standard” was implemented by the Supreme Court earlier this year to thwart the appointment of a Netanyahu ally as interior minister after he had recently pleaded guilty to tax offenses.

The court said the hearing concerning the law striking down the “reasonableness standard” would take place on Sept. 12 with a full bench of 15 justices. The Supreme Court typically hears cases with smaller panels of justices, but appears to have opted for a full complement of judges because of the highly delicate nature of the matter.

The Netanyahu administration’s push to overhaul the judiciary has deeply divided an already highly polarized country and sparked the longest sustained protests in the country’s history.

Netanyahu and his allies took office in December after the country’s fifth election in under four years, most of them referendums on the longtime leader’s fitness to serve while on trial for corruption.
