Proof step 8 from proof validstatfields-empty-01 (conclusion)

∀ class. tdname∃(str, class) → statfields(class) = [] ⊦ validstatfields(str, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ validstatfields(str, st) ↔ (∀ class. tdname∃(str, class) ∧ initdone(class, st) → validfieldlist(str, jvmref, statfields(class), st))
Proof step 7:
∀ class. tdname∃(str, class) → statfields(class) = [] ⊦ ∀ class. tdname∃(str, class) ∧ initdone(class, st) → validfieldlist(str, jvmref, statfields(class), st)

Rule argument

[crewrite-arg: validstatfields-def, F, [st, str] → [st, str]]
