“There is no doubt that by non-obstante clause the Legislature devices means which are usually applied to give overriding effect to certain provisions over some contrary provisions that may be found either in the same enactment or some other statute. In other words such a clause is used to avoid the operation and effect of all contrary provisions. The phrase is equivalent to showing that the Act shall be no impediment to measure intended. To attract the applicability of the phrase, the whole of the section, the scheme of the Act and the objects and reasons for which such an enactment is made has to be kept in mind.”
