This ACBL document ( Laws of Duplicate Bridge, 2008 ) talks about this on page 46
Assuming it is current
Looks like:
1. Double is canceled and replaced with something legal
2. Offender's partner must pass whenever it is his turn to call
3. "Law 23" and "Lead restrictions in Law 26" may apply
This is correct, but incomplete.
Although 5 seconds has passed the Director must first investigate if Law 25A (inadvertent call) applies.
Law 25A applies if North convinces the Director that it was never his intention to double, that he just pulled the unintended card from the bid box and only became aware of his mistake when attention was drawn to the irregularity.
(Replacing the "unintended" call with 1
♠ is a strong indication that the double does not qualify as unintended and inadvertent)
