CHAPTER VIII
The Score 

LAW 79 - TRICKS WON 

A. Agreement on Tricks Won

The number of tricks won shall be agreed upon before all four hands have been returned to the board.

B. Disagreement on Tricks Won

If a subsequent disagreement arises, the Director must be called. No increase in score need be granted unless the Director is called before the round ends as specified in Law 8 (but Law 69 or Law 71 may supersede this provision when there has been an acquiescence or a concession).

C.  Error in Score

An error in computing or tabulating the agreed-upon score, whether made by a player or scorer, may be corrected until the expiration of the period specified by the sponsoring organisation. Unless the sponsoring organisation specifies a later time, this correction period expires 30 minutes after the official score has been made available for inspection.
