You may not remember, but we’ve met once or twice over the years. I have also had some interest in the Principle of Symmetric Criticality, which has a fairly long history in the context of general relativity. In fact, Ian Anderson, Mark Fels and I did some relatively recent work on it. We found that if one restricts attention to local Lagrangian field theories, one can give a rather more detailed description of the obstructions to the principle. If you are still interested in this stuff, have a look here:
