That's a strange thing to say. The English regulations don't impose any obligations on a player who thinks his partner may have psyched.
I don't think that is strictly true.
I once lost an appeal when it was pretty obvious that partner (1-level, NV) was the one who was at it, rather than the opponents (4-level, V). But it took me a long time to work out just how obvious it was... finally I found a construction that involved my partner opening 1NT with a singleton (which I had never seen him do), and the opponents bidding with marginal values... so I doubled 4

Now partner pulled, exposing his psyche, but was deemed to have used UI (He had opened 1NT on something like an 8-count with 7 clubs). We submitted it to the NA and lost there too.
THe EBU policy basically dictates that if you psyche, you must lose out or you will be adjusted against.
