Dear Pulkit,
Certain statutory and mandatory documents like orders, permits, license etc., issued by any competent authority the period of operation of which is not restricted by time limit would be of permanent duration. Standing Orders certified under the IE(SO)Act,1946 is one such document which would be in operation throughout the life of the Industrial establishment concerned unless certain amendments are made either at the option of the employer or employees or both or as a result of amendment to the Act or its Rules by the Appropriate Government by way of deletion or addition of certain provisions relating to the conditions of employment. Even in the situation of amendment to the Act or Rules, only the the particular clause of the existing Standing Orders which is inconsistent with the amendment becomes inoperative and in case of introduction of a new clause, the existing Standing Orders has to be amended accordingly or no violation of the new provision shall be thereafter.
Model Standing Orders are not exhaustive but only illustrative to act as guide lines to frame the draft Standing Orders by the employer depending on the speciality or peculiarity of the activities of the establishment carried out through the employees. That's the reason for the certification of the D.S.O. In fact the model sta ding Orders Act as a stop-gap arrangement during the period between the dates of application of the Act and the certification of the draft Standing Orders.
Therefore, the question of surrendering the certified Standing Orders during its operation does not arise merely for the purpose of following the model Standing Orders.
