Proof step 21 from proof ac-out (previous step)

∀ class1, st, val. class1 = `java.lang.Object' .class ∨ addclass(class1, fis0, st[_out, val]) = (addclass(class1, fis0, st)[_out, val]) ⊦ class = class1, class1 = `java.lang.Object' .class, addclass(class1, fis0, st[_out, val]) = (addclass(class1, fis0, st)[_out, val])

Heuristic quantifier closing applied rule all left

And closed the goal!

Rule argument

[EXRARG : pos: left 1, [QUANTTERMLIST : (class1, st, val)]]
