Abstract
A natural deduction system for intuitionistic predicate logic with existential \ instantiation rule presented here uses Hilbert's -symbol. It is conservative over intuitionistic predicate logic. We provide a completeness proof for a suitable Kripke semantics, sketch an approach to a normalization proof, survey related work and state some open problems. Our system extends intuitionistic systems with -symbol due to A. Dragalin and Sh. Maehara.
