I've gone and done it.

In JOSM it gave a 412 Precondition Failed response - and didn't delete the 
way from the relation. So I opened Potlatch and it deleted it without any 
problem.

I've deleted the duplicate ways - I hope that was what you wanted to do. 
Presumably if there are duplicate ways everywhere (and I found 11 duplicates 
on top of each other in the UK where the route relation E20 had been 
created) - then this relation can be slimmed down anyway just by removing 
excess ways.
