Information arising from inferences that only become available because of the correction of misinformation is authorized to the non-offending side, but unauthorized to the offending side.
In addition; the WBF Systems Policy has also been revised with the following section f. being added to item 2.4 of the WBF Systems Policy:
For the avoidance of doubt an opening bid of one club which may be made on a doubleton or singleton club and which is ostensibly natural and non-forcing should be regarded as natural and not artificial
