select * from view _expandedsmartsafetrans where eventcode = 'DECL' and verifyid = 0 
UNION ALL
select v.* from view _expandedsmartsafetrans v cross apply (select top(1) * from _expandedsmartsafetrans vVer  
where vVer.eventCode = 'VER' and v.Verifyid = vVer.Id and vVer.PostingDate < @SomeDate order by vVer.PostingDate DESC) Ver
where v.eventcode = 'DECL'

This would not exclude rows if you have verfied afer the @SomeDate.
