It is just called Continuing Legal Education. You can go to lectures, you can even listen to tapes on airplanes - they want you to stay current. So you do have to stay current to maintain your license even if you are not practicing. ↗

At the end of the day, though, there are a huge number of considerations that our management team go through before accepting any project - checking out the license is just one of them. ↗
