A midnight curfew is fine. My 17 year old sister-in-law just ran away from home because she thinks she's an adopted slave. My in-laws adopted a set of three children, one boy and two girls all brother and sisters after taking care of them for years as foster parents. Recently they found out they were adopted. What's interesting is that they are half mexican/half indian while my parents are german, and they've been visiting their birth mother and maternal grandmother for years as part of the adoption agreement, yet they never caught on because my in-laws treat those kids very well. However, since they found out they were adopted, the oldest girl has been on an "I'm adopted." It got worse a few weeks before her 17th birthday when she decided she was nothing more than a slave. Her definition of slavery is having to fold one load of clothes, sweep the kitchen floor, and load the dishwasher with already rinsed dishes. Then it evolved into she's a slave and my father-in-law, a Marine, beats her. Now, my family and I spend enough time around the in-laws to know better, but it didn't stop her from telling all her friends and their parents that, which eventually got her boyfriends mother involved. The boyfriend's mom got it into her head that she could leave home at 17, so a week before her 17th birthday she informed my in-laws that she was moving out. That day came and went, and she was gone. Then the boyfriend ends up in the hospital numerous times for kidney problems, and boyfriends mom realises that the teenage girl is a spiteful manipulative PITA, and kicks her out. So, boyfriend and sister-in-law move in with boyfriend's sister, who also kicks them out. Finally, they end up at boyfriend's father's house, and after a week of tantrums, cursing fits, and violence he also kicks her out. So my mother-in-law picks her up and the fun really begins. She starts throwing fits, threatening to kill herself over this boy and other insane crap. Finally, she threaten's my mother-in-law and she calls the cops.
Bottom line: You're the father. Your wife may disagree with you all she wants, but ultimately most teenagers have the IQ of a bag of rocks and make horrible decisions. I had a 168 IQ at the age of 16, which was my last official test, and I made huge mistakes throughout my teens and early twenties until I straigthened up. You are the law. Parents MUST have a unified front. Otherwise your daughter gets mixed signals and knows she can play one against the other.
Sit down and tell your wife that you either agree or you will abstain from all decision making with the daughter and it will be her responsibiliy, including cleaning up the mess that comes of it.
Editied to add that I also agree with others on basing the curfew on her past judgement. If she's shown good judgement in the past, reward her now and again with a later curfew as a reward. But midnight on a weekend should be the norm. In my neck of the woods, most bad things happen between the hours of 12am-3am.
