JERUSALEM — Israel’s Supreme Court ruled Wednesday that Prime Minister Benjamin Netanyahu may form a new government while under indictment for corruption charges, clearing the way for him and his rival-turned-uneasy ally to join together in a controversial power-sharing deal.

The unanimous decision, released just before midnight, ended a 17-month political stalemate and prevented the country from plunging into a fourth consecutive election in just over a year. Netanyahu and his rival-turned-partner, Benny Gantz, said they expected their coalition to be sworn into office next week.

After battling to three inconclusive elections over the past year, Netanyahu and Gantz, a former military chief, announced their “emergency” government last month, saying they would put aside their rivalry to steer the country through the coronavirus crisis.

Critics and good-government groups said the deal was illegal and challenged it in the Supreme Court. They argued that the law should bar an official charged with serious crimes from continuing as prime minister. They also objected to the newly created position of “alternate prime minister,” a post that could allow Netanyahu to remain in office throughout his corruption trial and a potential appeals process.

Over two days this week, the court looked at two questions: whether an indicted politician can be given authority to form a new government, and whether the power-sharing deal — which includes new legislation — was legal.

In its decision, the 11-judge panel expressed misgivings about the coalition agreement and Netanyahu’s criminal indictment, but found no grounds to prevent the government from taking office.

“We did not find any legal reason to prevent MK (Member of Knesset) Netanyahu from forming a government,” the court said.

Netanyahu Has Been Indicted With Fraud, Breach of Trust and Accepting Bribes

“The legal conclusion we reached does not diminish the severity of the pending charges against MK Netanyahu for violations of moral integrity and the difficulty derived from the tenure of a prime minister accused of criminal activity,” it added.

The judges ruled that while the coalition deal presents significant legal difficulties, the court would not interfere in its contents following changes submitted by Netanyahu and Gantz.

Netanyahu has been indicted with fraud, breach of trust and accepting bribes in a series of scandals involving trading favors with wealthy media moguls. His trial is set to start later this month.

Netanyahu denies any wrongdoing, and since his indictment last fall, he has repeatedly lashed out at the country’s legal system. He and his political allies have taken special aim at the high court, accusing it of overreach and political interference.

As the court was meeting earlier this week, Netanyahu urged it not to get involved in political affairs, lest it risk dragging the country toward new elections. The long-time leader’s opponents consider the court a bastion of democracy under dangerous assault and had expressed hope it would strike down what they see as a deal that undermines the public’s faith in government.

Eliad Shraga, a lawyer representing one of the petitioners against the coalition deal, expressed disappointment but said he would respect the decision. “We will continue to raise the flag of morality,” he told Channel 12 news.

With the court hurdle cleared, Netanyahu and Gantz must complete two more procedural steps before they can move ahead with their deal: pass the legislation needed to pave the way for their convoluted coalition agreement and amass the signatures of 61 lawmakers — a parliamentary majority — in favor of Netanyahu as prime minister-designate to be sent to Israel’s ceremonial president by a midnight Thursday deadline.

With more than a majority of the Knesset’s support, including from Gantz’ party, both steps appear to be easily attainable.

Throughout three bruising campaigns, Gantz repeatedly vowed never to sit in a government with Netanyahu. And after March elections, a narrow majority of lawmakers endorsed him as prime minister. Gantz began preparing legislation that would have banned Netanyahu from continuing as prime minister.

Under the Deal, Netanyahu and Gantz Would Be Sworn in Together

But in a sudden about face, Gantz accepted an invitation to form a partnership with Netanyahu to confront the coronavirus crisis, infuriating many of his supporters and causing his Blue and White party to split in half.

Last month, the two sides agreed on a coalition deal that makes the two men equal partners, with virtual veto power over each other’s decisions. Because of its unorthodox arrangement, the Knesset must pass new legislation before they take office.

Under the deal, Netanyahu and Gantz would be sworn in together, with Netanyahu serving first as prime minister and Gantz as the designated premier. After 18 months, the two are to swap positions. The new position will enjoy all the trappings of the prime minister, including an official residence and, key for Netanyahu, an exemption from a law that requires public officials who are not prime minister to resign if charged with a crime.

Netanyahu is eager to remain in office throughout his trial, using his position to lash out at the judicial system and rally support among his base. The coalition deal also gives him influence over key judicial appointments, creating a potential conflict of interest during an appeals process if he is convicted. His trial was postponed in March due to restrictions his hand-picked interim justice minister placed on the courts after the coronavirus crisis erupted and is scheduled to commence later this month.

The court said Netanyahu would need to abide by a conflict of interest arrangement while prime minister whenever dealing with law enforcement affairs.

Under the deal, the sides agreed not to take immediate action on key appointments and prioritize legislation focusing on reviving Israel’s economy from the coronavirus crisis.

But it makes an exception for Netanyahu to press ahead with plans to annex large parts of the West Bank, including all of Israel’s dozens of settlements there. Netanyahu is permitted to push the issue through parliament after July 1, even without Gantz’s support.

Netanyahu and his hardline supporters are eager to annex the territory while the friendly administration of U.S. President Donald Trump is in office. The Palestinians and most of the international community oppose annexation and say it would end any lingering hopes of a peace deal.
