Need advice.

H always says that he is never allowed to decide anything. DD's phone was taken away from him b/c of her grades. I allowed her to have her phone on a school field trip and he was not too happy. I should have asked him permission but I didn't. Now DD is going away for the weekend, she called her dad to ask if she could take her phone and he told her to ask me because I'm the boss. How do I respond?? I feel like he can tell her no himself, but wants to put the pressure on me and if I say yes, he will keep playing the "I never get a say in anything" card. Help!!!!
