Idea

A consequent or conclusion judgement on the right of the ” $⊢$ “-symbol of a sequent/hypothetical judgement: a judgement that is a consequence of the antecedent judgements on the left of the symbol.

If there is more than one disjunctively connected consequent, these are called the succedents.

antecedents $⊢$ consequent
