Nuprl Lemma : consensus-state3-unequal
∀[V:Type]
((¬(INITIAL = WITHDRAWN ∈ consensus-state3(V)))
∧ (∀[v:V]
(((¬(COMMITED[v] = INITIAL ∈ consensus-state3(V))) ∧ (¬(CONSIDERING[v] = INITIAL ∈ consensus-state3(V))))
∧ (¬(COMMITED[v] = WITHDRAWN ∈ consensus-state3(V)))

Proof
Definitions occuring in Statement :
cs-commited: COMMITED[v],
cs-considering: CONSIDERING[v],
cs-withdrawn: WITHDRAWN,
cs-initial: INITIAL,
consensus-state3: consensus-state3(T),
uimplies: b supposing a,
uall: ∀[x:A]. B[x],
not: ¬A,
and: P ∧ Q,
universe: Type,
equal: s = t ∈ T
