“The Secretary of State shall from time to time….lay before Parliament statements of the rules, or of any changes in the rules, laid down by him as to the practice to be followed in the administration of this Act for regulating the entry into and staying in the United Kingdom of persons required by this Act to have leave to enter, including any rules as to the period for which leave is to be given and the conditions to be attached in different circumstances….

“it is not necessarily to be regarded as the normal practice, where delegated legislation is held to be ultra vires, to revoke the instrument, that …..the inclination would be the other way, in the absence of special circumstances making it desirable to revoke that instrument….in principle I treat the matter as one of pure discretion….” 41. It has proved difficult to find other authority on the specific point. Webster J’s dictum does not seem to be discussed, much less adopted, in any of the standard works on administrative law, and for my part I would not wish to endorse it. As with any administrative decision, the Court has discretion to withhold relief if there are pressing reasons for not disturbingthe status quo. It is, however, wrong to think that delegated legislation has some specifically protected position in that respect. If anything, the imperative that public life should be conducted lawfully suggests that it is more important to correct unlawful legislation, that until quashed is universally binding and used by the public as a guide to conduct, than it is to correct a single decision, that affects only a limited range of people.”
