Still the best analogy I can think of is a Marriage. If you plan to marry while underage you need the written consent of one of the parents.
Can a refusal somehow stop or delay the process while the local elders get advice from the legal department?
Although I am not an expert in this area of law, the analogies that have been used are incorrect and my guess would be the answer is simply no.
First marriage is governed by laws that are in place, hence the need to obtain permission for under aged marriage. As for a "contract" last I know of, when you get btzd there is nothing you are signing and my guess is getting btzd is not the same as entering into a verbal contract. You are answering questions, but they are not questions you are being asked to swear to, you are not providing a witness statement nor are you giving a deposition.
Again, my quick response w/o doing research is no. You may find someone here that has actually looked into it and they may have an answer. Regardless, I would want the back up, just in case you have to fight the issue. Make sure they have your state correct and they provide with either the Statute that is appropriate and/or case law.
