∀[Info:Type]. ∀[es:EO+(Info)]. ∀[e:E]. (e ∈b prior(E) ~ ¬bfirst(e))
Proof
Definitions occuring in Statement :
es-prior-interface: prior(X),
es-all-events: E,
in-eclass: e ∈b X,
event-ordering+: EO+(Info),
es-first: first(e),
es-E: E,
bnot: ¬bb,
uall: ∀[x:A]. B[x],
universe: Type,
sqequal: s ~ t
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
uimplies: b supposing a,
es-all-events: E,
es-prior-interface: prior(X),

local-pred-class: local-pred-class(P),
all: ∀x:A. B[x],
top: Top,
eq_int: (i =z j),
es-local-pred: last(P),
ifthenelse: if b then t else f fi ,
btrue: tt,
subtype_rel: A ⊆r B,
implies: P ⇒ Q,
bool: 𝔹,
unit: Unit,
it: ⋅,
uiff: uiff(P;Q),
and: P ∧ Q,
bnot: ¬bb,
