Considering a logic I- cast as a Tarskian consequence relation between sets of formulas and formulas, there are several ways how to construct its symmetric version II- with a disjuncture flavour on the right-hand side. The
situation becomes even more complex if the logic in question is infinitary. Dunn and Hardegree showed that the proper Cut rule for such symmetric logic is equivalent to Pair Extension Property which plays a crucial rule in the completeness proofs for many modal logics.
