The government Sunday unveiled proposed incentives to encourage ultra-Orthodox yeshiva students to join the army, but the High Court of Justice judges hearing the proposals criticized the new law for having all carrots and no sticks: It includes no sanctions for yeshivas whose students don’t enlist.

Commenting that the law essentially makes the draft “voluntary,” Justice Uri Shoham asked, “If it’s voluntary, why do you need a law at all?”

The High Court hearing was held on several petitions against the new conscription law passed in November.

The incentives, proposed by an inter-ministerial task force, include housing assistance for ultra-Orthodox men who enlist, extra funding for yeshivas whose students enlist, and training programs to prepare ultra-Orthodox enlistees for the labor market.
