SECTION 17. DISCIPLINARY PROCEDURES:   The Master shall furnish the seafarer with the following disciplinary procedure against an erring seafarer:   A. The master shall furnish the seafarer with a written notice containing the following:   1. Grounds for the charges as listed in Section 31 of this Contract.   2. Date, time and place for a formal investigation of the charges against the seafarer concerned.   B. The Master or his authorized representative shall conduct the investigation or hearing, giving the seafarer the opportunity to explain or defend himself against the charges. An entry on the investigation shall be entered into the ships logbook.   C. If after the investigation or hearing, the Master is convinced that imposition of a penalty is justified, the Master shall issue a written notice of penalty and the reasons for it to the seafarer, which copies shall be furnished to the Philippine Agent.   D. Dismissal for just cause may be effected by the master without furnishing the seafarer with notice of dismissal if doing so will prejudice the safety of the crew or the vessel. This information shall be entered in the ships logbook. The Master shall send a complete report to the manning agency substantiated by the witnesses, testimonies and any other documents in support thereof.     In this case, there was no showing that Celtic complied with the foregoing procedure, thus, casting a serious doubt on the validity of De Jesus discharge.   Likewise, neither the ships logbook nor the report sent to POMI as Celtics manning agent was presented in the proceedings a quo to establish the breach committed by De Jesus. The pieces of evidence submitted before the Labor Arbiter in support of De Jesus discharge zeroed in on the alleged misrepresentation, which, as mentioned, cannot be a valid basis for the denial of De Jesus claims.
