When
an offending player’s call is withdrawn, and he chooses a different* final call for that turn, then if he becomes a defender:
A.
Call Related to Specific Suit
if the
withdrawn call related solely to a specified suit or suits (and no other suit),
and
1. if each such suit
was specified in the legal auction by the same player there is no lead
restriction, but see Law 16D.
2.
if any suit specified in the withdrawn call was not
specified by the same player in the legal auction then, at offender’s partner’s
first turn to lead (which may be the opening lead), declarer may either,
(a) require the
offender’s partner to lead such a suit (if there are more than one declarer
chooses the suit; or
(b) prohibit
offender’s partner from leading (one) such suit. Such prohibition continues for
as long as the offender’s partner retains the lead.
B.
Other Withdrawn Calls
For other withdrawn
calls, declarer may prohibit offender’s partner from leading any one suit at
his first turn to lead, including the opening lead, such
prohibition to continue
for as long as offender’s partner retains the lead.
* A call repeated with
a much different meaning shall be deemed a different call.
