Legal call/ legal bid
Could someone define me the meaning of 'legal call" and "legal bid' which are used in many Laws, but I think without a specific definition?
For example law 27C reads:
"If the offender replaces his insufficient bid before the Director has ruled on rectification the substitution, if legal, stands unless..."
If this replacing bid is insufficient, is it legal or not? Insufficient is defined as an infraction, but does that mean that it is an illegal bid also?
An illegal bid I think could be 8NT! An illegal cal could be a double on partner's bid.
