Proof step 19 from proof newref-exists (previous step)

jvmref < r0, r < r1, jvmref < r1, ∀ r0. r0 ∈ st → r0 < r, ∀ r. ∃ r0. r < r0 ⊦ r < jvmref, ∃ r. newref(r, st)

User applied rule exists right

And obtained the following new goals

Proof step 18:
jvmref < r0, r < r1, jvmref < r1, ∀ r0. r0 ∈ st → r0 < r, ∀ r. ∃ r0. r < r0 ⊦ r < jvmref, newref(r1, st)

Rule argument
