Both parts of the Discovery Act’s sanctions chapter, CCP 2023.010 lists the types of discovery abuses the Legislature sought to preclude, and CCP 2023.030 lists the types of sanctions that can be awarded if authorized by a later section governing a specific discovery device, but neither of these general sections, in itself or combined with each other, authorizes imposition of sanctions. Instead, sanctions may be awarded only to the extent authorized by a later section governing a specific discovery device. Exceptions to that general rule exist only for cases in which (a) a party has lulled the opponent into not pursuing further discovery by assuring it falsely that full responses have already been provided, (b) a party has prevented discovery unavailable as by spoliation, or (c) a lawyer has supplied a witness with answers at a deposition. Courts lack inherent authority to impose sanctions other than as authorized by the Discovery Act for discovery abuse. After a case is dismissed, the court retains jurisdiction to award monetary discovery sanctions in connection with discovery motions that it granted during the pendency of the case. The e timeliness of a motion for discovery sanctions based on a discovery ruling during the action is a matter within the discretion of the trial court.
