Proof step 35 from proof addobj-union-rew (previous step)

newref(r, st), newref(r, st0) ⊦ r = jvmref, (rk ∈ addobj(r, class, fis, st ∪ st0) ↔ rk ∈ st ∨ rk ∈ addobj(r, class, fis, st0)) ∧ (addobj(r, class, fis, st ∪ st0)[rk]) = (st ∪ addobj(r, class, fis, st0))[rk]

User applied rule structural induction

And obtained the following new goals

Proof step 34:
newref(r, st), newref(r, st0) ⊦ r = jvmref, (r0 -- sk ∈ addobj(r, class, fis, st ∪ st0) ↔ r0 -- sk ∈ st ∨ r0 -- sk ∈ addobj(r, class, fis, st0)) ∧ (addobj(r, class, fis, st ∪ st0)[r0 -- sk]) = (st ∪ addobj(r, class, fis, st0))[r0 -- sk]

Rule argument
