The act or process of reversing an annulment; the invalidation of a previous nullification or void judgment.
From disannul + -ment suffix (forming abstract nouns of states or results). The -ment suffix comes from Latin -mentum.
Disannulment is actually rarer than annulment in modern law because it essentially undoes a previous legal decision, which courts prefer to avoid since it creates uncertainty about which judgment was actually correct.
