Strong pass system. 1♣ showed ♥s, 8-12 pts.
4♥ came after some thought, then 4♠ & double followed "in quick succession."
No screens, no alerts beyond 3NT.

The problem for EW is the meaning of double.
Systemically it means "I have high ODR, I'm happy to be at the 5-level."
It's a good method but West forgot, quickly.
Declarer called the director at the end and suggested that East should have bid 5♥.
That the decision to pass might have been influenced by the quick double.
East admitted that partner had a record of forgetting this agreement but that it was a verbal agreement, not in the system notes.
Director went away and polled a few of East's peers.
What did he rule?
