Ertai's Meddling has the spell's controller put the spell back onto the stack; it does not have its controller cast the spell again. Anything that triggers off of casting spells, such as Contemplation , won't trigger. Simillarly, effects that count spells that are cast (like Rule of Law) or prevent spells from being cast (like Iona, Shield of Emeria) won't count or affect the copy that is put onto the stack since the copy wasn't cast.
