The school is correct. Without a restraining order, they can actually get into trouble for not releasing the kids to Dad/his agent.
They don't care about your court order, since it's irrelevant.
If you want to modify the order, take it back to court.
Now. If he's taking the children and keeping them from you when it's your parenting time, that's another issue entirely.
Well...since dad's parenting time never starts until 6PM he or his "agent" are definitely violating the court orders if either one of them are picking up the children from school.
I am thoroughly familiar with the arguments made by a family law attorney that a school cannot refuse to release the children to either parent unless there is a restraining order, without getting into trouble.
However, lets break that argument down. The school's response to the parent is "I am sorry but we have a copy of your custody orders and you do not have the right to access the children during school hours". First possible reaction: The parent in question calls the police to the school. The police arrive. The school explains their position. What is the likely response of the police? Will the police clearly facilitate the violation of the court orders by ordering the school to turn the children over to the parent? Or will the police say "civil matter between the parents we won't get involved"? Remember, this is a parent with no legal or physical custody and defined, specific access to the children.
Second possible reaction: The parent in question sues the school for not releasing the children. What defense is going to be raised in the civil suit? The court order and the testimony of the custodial parent. Can a judge actually find in favor of the suing parent when they were clearly violating a custody order that gives that parent defined and specific access to the children that does not include school hours?
Lets get rid of all gender issues on this one...because gender issues are moot. What is the school's greatest risk both criminally and civilily?
I can certainly understand a school deciding that they will NOT police custody orders. However, at the same time I think that the school's risk is much higher if they refuse to acknowledge situations where one of the parents has no legal or physical custody and has defined access.
