Narrative:
We were on noise abatement procedures for midnight operations off ZZZ and ZZZ1. I told ZZZ to hold their night departures because they instantly conflict with ZZZ1 departures. Then I gave ZZZ1 a departure release. About 4 minutes go by and I see a target climbing off of ZZZ. I get a call from ZZZ apologizing for launching an aircraft. On initial contact I turn the ZZZ departure east to a 050 heading because my ZZZ1 departure is climbing fast. If I had not gotten communication when I did they could have potentially hit. As it was I believe standard separation was still lost between the two departures. ZZZ failed to follow a control instruction resulting in an unsafe situation.the noise abatement departure off ZZZ and ZZZ1 are designed in a way that they automatically conflict. I would not be surprised if there is a long history of conflicts like this.
