California Code, Education Code - EDC § 45116

A notice of disciplinary action shall contain a statement in ordinary and concise language of the specific acts and omissions upon which the disciplinary action is based, a statement of the cause for the action taken and, if it is claimed that an employee has violated a rule or regulation of the public school employer, such rule or regulation shall be set forth in said notice.

A notice of disciplinary action stating one or more causes or grounds for disciplinary action established by any rule, regulation, or statute in the language of the rule, regulation, or statute, is insufficient for any purpose.

A proceeding may be brought by, or on behalf of, the employee to restrain any further proceedings under any notice of disciplinary action violative of this provision.

This section shall apply to proceedings conducted under the provisions of Article 6 (commencing with Section 45240) of this chapter.
