That's a very good question! There are a lot of forgeries out there which have previously been expertized as genuine by renowned experts in the field and later turned out to be fakes. This complicates matters even more... Most auctioneers will not accept returns of the previously expertized items even if they are not marked as "FORGERY" on the back by LPS.
In the past what I have done was discuss with the auctionhouse first if they would accept an opinion of a particular expert who I wanted to use... If they did not - I asked who would they be comfortable with... But if a fake has Krischke's certificate, I am afraid you are stuck
