I haven't come across any that took 10 years, but I've seen five years. A lot of requests take between one and five years to get resolved, and that's true for a number of departments.
Take, for example, the complaint we filed in 2012, which I mentioned earlier. It took five or six years for the commissioner to ask us whether we still wanted the records in question. We said yes. We weren't going to change our mind and drop the complaint because the commissioner made us wait six years. We wanted to get the records; we wanted that information.
After we heard from the commissioner, we had to wait another few years to get the records. We received the information we had requested 10 years after our initial request.
