Declarer plays two cards at once

[barmar]

I'll wager that whoever chose to use the phrase "highest ranking" in 67B2a simply didn't think of this corner case. You have to have a defective trick where cards from different suits were played, not notice it until after both sides have played to the next trick, and not be able to determine which of the cards was actually faced -- how often does that happen?

 

BTW, does anyone have a link to old versions of the Laws? I wanted to see how far back this does, but my 1997 copy is on bridgeguys.com, which they failed to renew last month.
