I don't think the law sees trying to assert your legal rights is taken as a threat Dave, even though it may appear to be so. I think unless it was presented as a threat it could be construed as such.
We did ban a member from my club when I was chair for that though. Their point was quite legitimate, but it was the manner of asking, so we permanently banned them. It was over £50 that they thought they were owed. In the end they weren't. It was a shame as we then were duty bound to report them to their FEO, so they probably lost their guns as well. Amazing what some people are willing to wreck in an attempt to prove a point.
