The Movement for Integrity on Sunday petitioned the High Court of Justice to overturn President Reuven Rivlin's decision to ask Prime Minister Benjamin Netanyahu to form the next coalition.
In its appeal, the left-wing NGO asked the court to rule that tasking Netanyahu to form the next government is illegal.
The petitioners also argued that the current situation is detrimental to the rule of law in Israel.
The Movement for Integrity predicated its petition on the series of corruption charges which Netanyahu is facing, and Attorney General Avichai Mendelblit's decision to indict him pending a hearing.
The petition additionally cited precedential rulings by the Supreme Court.
Those rulings stipulate, among other things, that it is unreasonable for any individual under indictment for such offenses to serve as a minister or any other senior capacity in government.
The petitioners emphasized that they do not seek to call into question the result of the election, because in Israel the public votes for parties and not the prime minister.
Finally, the Movement for Integrity asked the court to establish obligatory parameters pertaining to appointing someone to form a government.
