(b) Except as provided in subdivisions (c) and (d), a protest shall not be canceled for failure to submit information not in the possession or under the control of the protestant if the protest is in compliance with Section 1331 and the applicant is or could be required to submit the information under Section 1260 or 1275. (c) If a protest is based on interference with a prior right, the board may cancel the protest if the protestant fails to submit any of the following information requested by the board: (1) Information that the protestant is required to submit to the board to comply with Part 5.1 (commencing with Section 5100) during any period after the protest is filed. (2) Information that is reasonably necessary to determine if the protestant has a valid water right.
