Lawyers aren't a protected group. Just like men, white people, and rich people.
Having said that, don't be surprised if a lawyer massages his way into your building and trips on a wet floor and sues you for $50,000. That is their special talent.
Depends on your jurisdiction, in some places equality law specifically says you can't discriminate based on gender, race, nationality, etc. However I'm not aware of any equality law that includes professions, so you'll be fine
