Dear Narendra,
I am not able to understand the hypothetical situation described by you.
Understanding Model Standing Orders
Model Standing Orders are there only to be taken as a guideline when the employer drafts his Standing Orders and submits the same for certification. While framing the Draft Standing Orders (DSO), it is not necessary that it shall be a mere replica of the Model Standing Orders (MSO).
Variations and Certification Process
There can be variations in certain conditions depending on the particular industrial requirements. If it is objected to by the workmen/trade union participating in the certification process, the certifying officer will decide the issue based on the points of justification advanced on either side.
Legal Compliance and Amendments
If any particular clause of the DSO is against the provisions of any law, principles of natural justice, or empowers the employer with arbitrary powers, the Certifying Officer (C.O) will not certify it. Even in the future, if any clause of the certified Standing Orders (S.O) becomes inconsistent with subsequent amendments carried out to any law applicable to the industrial establishment, such a clause, though certified earlier, will not have operation to the extent of inconsistency.
If any subsequent amendments create any special rights, obligations, benefits, etc., they can be added to the S.O by means of the amendment process. Even a single workman can move an amendment.
