Narrative:
Flight en route to lax was cleared direct civet and civet profile. Then reclred direct civet direct baset, cross civet at or above 14000 ft, baset at 10000 ft. (Due to time of day, approach would be over water to land east instead of straight in to land west.) shortly after previous clearance flight reclred direct santa monica. Soon after this clearance, ATC reminded flight that it was cleared to cross civet after above 14000 ft. Flight, at first responded that it was by civet since civet was no longer on EFIS. Then flight reminded ATC that it had been reclred direct santa monica and therefore previous clearance no longer in effect. No crossing restriction was issued on next clearance, just direct santa monica. Flight proceeded direct to santa monica and descended to 10000 ft as cleared. Have reason to believe ATC controller forgot direct santa monica clearance had been issued. Supplemental information from acn 193793: we reminded the controller that we had been cleared direct to the santa monica VOR and that the crossing restriction at civet is deleted since civet was no longer a part of our clearance. The controller said we were correct.

Title: ACR WDB ALTDEV XING RESTRICTION NOT MET ON PROFILE DSCNT WITH AMENDED CLRNC RTE INTO LAX.
Narrative: FLT ENRTE TO LAX WAS CLRED DIRECT CIVET AND CIVET PROFILE. THEN RECLRED DIRECT CIVET DIRECT BASET, CROSS CIVET AT OR ABOVE 14000 FT, BASET AT 10000 FT. (DUE TO TIME OF DAY, APCH WOULD BE OVER WATER TO LAND E INSTEAD OF STRAIGHT IN TO LAND W.) SHORTLY AFTER PREVIOUS CLRNC FLT RECLRED DIRECT SANTA MONICA. SOON AFTER THIS CLRNC, ATC REMINDED FLT THAT IT WAS CLRED TO CROSS CIVET AFTER ABOVE 14000 FT. FLT, AT FIRST RESPONDED THAT IT WAS BY CIVET SINCE CIVET WAS NO LONGER ON EFIS. THEN FLT REMINDED ATC THAT IT HAD BEEN RECLRED DIRECT SANTA MONICA AND THEREFORE PREVIOUS CLRNC NO LONGER IN EFFECT. NO XING RESTRICTION WAS ISSUED ON NEXT CLRNC, JUST DIRECT SANTA MONICA. FLT PROCEEDED DIRECT TO SANTA MONICA AND DSNDED TO 10000 FT AS CLRED. HAVE REASON TO BELIEVE ATC CTLR FORGOT DIRECT SANTA MONICA CLRNC HAD BEEN ISSUED. SUPPLEMENTAL INFO FROM ACN 193793: WE REMINDED THE CTLR THAT WE HAD BEEN CLRED DIRECT TO THE SANTA MONICA VOR AND THAT THE XING RESTRICTION AT CIVET IS DELETED SINCE CIVET WAS NO LONGER A PART OF OUR CLRNC. THE CTLR SAID WE WERE CORRECT.
