I'm sorry, I'm still getting nowhere on this one. I had YEAS, assuming it was say (=state) reversed, then the additional "e". Are we looking for an abb. for a body that looks into legal cases & whether there is a "prima facie" case? I fear the abbreviation is probably completely unknown to me (living abroad as I do) & a long search through the available lists online has produced nothing. I'm assuming now that "power" is "P". Then it can only be ?EPS, right? Please put me on the right track: this is driving me mad!
