It depends on how the order is written.
If NCP has joint legal custody, then s/he has the right to be involved with legal decisions relating to the child - but there's one very important caveat here. Joint legal DOES NOT mean that if the parent disagrees, it must go before the court. If one parent is given veto power for example, it effectively makes the whole thing moot since s/he can make decisions regardless of the other parent's concerns.
If the CP has sole legal custody, even then it sometimes means the NCP can have input...but obviously no power to actually make the decision.
It call comes down to how the order is written.
