CALTA Rules vs. USTA/LCTA Rules

CALTA's Rules state that, when a specific on-court situation is not covered by CALTA Rules, USTA Rules/Code will apply. 
Reflecting the basic philosophical differences between the two organizations, CALTA, as a social league, has some rules that are different from USTA -- and captains are asked to make sure that their players are familiar with these rules ...

Ratings:  CALTA does not use NTRP ratings.  A player can play in any division.

Player Transfers:  A player can transfer from one team to another (once) during the season.

Court Surface Notification:  If a facility will use both clay and hard courts for a match, CALTA's Rule VI states: "Clubs that have courts with different surfaces shall let the visiting team know which positions will be playing on which surfaces before line-up exchange.  If this information is not shared before line-up exchange, each captain has the option of changing her line-up."

Weather (temperature) rule:  Players are not required to compete when it is very hot or very cold -- and that decision can be made individually by each player ...see CALTA's Rule XII.

Third Set:  As with most ladies' social leagues in the U.S., CALTA is a 3-set league.  CALTA's Rule VIII states that, if a match is "split" after two sets, the players may want to discuss the possibility of playing a 10-point "match tie-break" (using the Coman format) instead of a full third set.  (It need not be discussed prior to that point.)  The decision to play a match tie-break instead of a third set must be willingly unanimous.  If any of the four players objects, a third set must be played. 

Grievances:  CALTA has a Grievance Committee but does not allow for appeals of its decisions.

Timing between games:  CALTA specifies a 90-second break after the first game of a set.

Grace period for arrival:  CALTA allows a 15-minute grace period for an emergency (Rule VI).

Waiting period when rain interrupts a match:  If rain interrupts a match, CALTA does not require that players wait an hour to determine court playability. 

Make-up deadline:  CALTA does not require that make-ups be played within two weeks of the originally scheduled match.  If the official make-up dates scheduled on the CALTA calendar are not able to be used by a team for valid reasons, there is no official  deadline and there is no penalty if teams mutually decide to not play a match.  

Phone/pager interruption:  CALTA's Rule here is "tougher" than in USTA.  CALTA's Rule VIII says "Cellular phones and pagers must be set to vibrate or silent.  A penalty of one point will be imposed if a phone rings ..."
Rules disputes during a match:  Disagreements about line calls or scores are, of course,  to be discussed only by the players but, in CALTA, disagreements about rules can be referred by anyone on the court to a captain or her designated representative (see Rule VIII).  If possible, the captain (or her designated representative at the match) is expected to take the initiative to assist the players in identifying the pertinent rule.

In the "CALTA spirit", there is an emphasis on hospitality and communication ...
Rule IV covers  the required pre-match communication between captains -- and also states that the host team furnishes light refreshments.

Community Support:  Each CALTA team is asked to donate at least one item to the raffle at the year-end luncheon.  100% of the receipts from the raffle are allocated to support junior girls' tennis in the Charleston Area.
