Protesters objected that byelaws which had been made to prevent access to common land, namely Greenham Common were invalid.
Held: The byelaws did prejudice the rights of common. The House was concerned to clarify the test applicable when seeking to sever the valid from the invalid where part of subordinate legislation, the RAF Greenham Common Byelaws, was held to be ultra vires the enabling statute.
The fact that the invalid feature of the byelaw could not be excised with a blue pen did not preclude severance. What precluded it was that, if the byelaw was so construed as to allow the 62 commoners to enter the land, the legislative purpose behind it would be undermined.
The House set out a test of ‘substantial severability’ which the byelaws failed. Lord Bridge said: ‘When a legislative instrument made by a law-maker with limited powers is challenged, the only function of the court is to determine whether there has been a valid exercise of that limited legislative power in relation to the matter which is the subject of disputed enforcement. If a law-maker has validly exercised his power, the court may give effect to the law validly made. But if the court sees only an invalid law made in excess of the law-maker’s power, it has no jurisdiction to modify or adapt the law to bring it within the scope of the law-maker’s power. These, I believe, are the basic principles which have always to be borne in mind in deciding whether legislative provisions which on their face exceed the law-maker’s power may be severed so as to be upheld and enforced in part.
The application of these principles leads naturally and logically to what has traditionally been regarded as the test of severability. It is often referred to inelegantly as the ‘blue pencil’ test. Taking the simplest case of a single legislative instrument containing a number of separate clauses of which one exceeds the law-maker’s power, if the remaining clauses enact free-standing provisions which were intended to operate and are capable of operating independently of the offending clause, there is no reason why those clauses should not be upheld and enforced. The law-maker has validly exercised his power by making the valid clauses. The invalid clause may be disregarded as unrelated to, and having no effect upon, the operation of the valid clauses, which accordingly may be allowed to take effect without the necessity of any modification or adaptation by the court. What is involved is in truth a double test. I shall refer to the two aspects of the test as textual severability and substantial severability. A legislative instrument is textually severable if a clause, a sentence, a phrase or a single word may be disregarded, as exceeding the law-maker’s power, and what remains of the text is still grammatical and coherent. A legislative instrument is substantially severable if the substance of what remains after severance is essentially unchanged in legislative purpose, operation and effect. ‘ and ‘The test of textual severability has the great merit of simplicity and certainty. When it is satisfied the court can readily see whether the omission from the legislative text of so much as exceeds the law-maker’s power leaves in place a valid text which is capable of operating and was evidently intended to operate independently of the invalid text. But I have reached the conclusion, though not without hesitation, that a rigid insistence that the test of textual severability must always be satisfied if a provision is to be upheld and enforced as partially valid will in some cases . . have the unreasonable consequence of defeating subordinate legislation of which the substantial purpose and effect was clearly within the law-maker’s power when, by some oversight or misapprehension of the scope of that power, the text, as written, has a range of application which exceeds that scope. It is important, however, that in all cases an appropriate test of substantial severability should be applied. When textual severance is possible, the test of substantial severability will be satisfied when the valid text is unaffected by, and independent of, the invalid. The law which the court may then uphold and enforce is the very law which the legislator has enacted, not a different law. But when the court must modify the text in order to achieve severance, this can only be done when the court is satisfied that it is effecting no change in the substantial purpose and effect of the impugned provision.’
