As I have written before, the question of whether mandatory membership in a bar association violates the First Amendment is not a new issue, so it is interesting that it is making such a strong comeback. At one point I think I labeled it the "hot issue" of the year because I kept seeing reports of lawsuits being filed around the country.
A few days ago, a decision from the 8th Circuit may have slowed down the trend a bit (in a case originating in North Dakota), but there are still a bunch of cases pending out there. At last count, there were challenges filed in Texas, Oklahoma, Oregon, Wisconsin, Louisiana, Washington and Michigan.
