Forum:Rituals from the g-yard?

Can a ritual monster be SS from the graveyard if everything else is the same as a normal ritual summon? in my case my opponent already ritual summoned relinquished completely legitimately and i destroyed it, he then (later in the duel) used another black illusion ritual he had to SS it from the graveyard. i've looked at the ver. 7.0 rules and on multiple ritual cards and none of them indicate if this is legal or not. thanks Stigles 01:45, 30 August 2009 (UTC)
