The article aims at analysing the relevant presence of juridical categories in Levinas’s Philosophy and at reconducting them to their phenomenological premises. The essay is divided in four parts: 1. justice, right and law; 2. the collapse of the law; 3. explanation thanks to the biblical figure of Ritzpa Bath Ajà; 4. conclusions about the levinasian contribution to the studies on vulnerability. For Levinas, vulnerability represents the phenomenological premise to think the collapse of the law, when right is exposed to what it cannot contain, to the significance of the justice.
