Proof step 10 from proof newrefs-in (previous step)

∀ r, st. ¬ (r ∈ st ∧ r ∈ newref_list(m, st)) ⊦ ¬ (r ∈ st ∧ r ∈ newref_list(m +1, st))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 9:
r ∈ st, r ∈ newref_list(m + 1, st), ∀ r0, st0. ¬ r0 ∈ st0 ∨ ¬ r0 ∈ newref_list(m, st0) ⊦

Rule argument
