Later on Bennion says:[1]
‘Each generation lives under the law it inherits. Constant formal updating is not practicable, so an Act takes on a life of its own. What the original framers intended sinks gradually into history. While their language may endure as law, its current subjects are likely to find that law more and more ill-fitting. The intention of the originators, collected from an Act's legislative history, necessarily becomes less relevant as time rolls by. Yet their words remain law. Viewed like this, the ongoing Act resembles a vessel launched on some one-way voyage from the old world to the new. The vessel is not going to return; nor are its passengers. Having only what they set out with, they cope as best they can. On arrival in the present, they deploy their native endowments under conditions originally unguessed at.
In construing an ongoing Act, the interpreter is to presume that Parliament intended the Act to be applied at any future time in such a way as to give effect to the true original intention. Accordingly the interpreter is to make allowances for any relevant changes that have occurred, since the Act's passing, in law, social conditions, technology, the meaning of words, and other matters. Just as the US Constitution is regarded as “a living Constitution”, so an ongoing British Act is regarded as “a living Act”. That today's construction involves the supposition that Parliament was catering long ago for a state of affairs that did not then exist is no argument against that construction. Parliament, in the wording of an enactment, is expected to anticipate temporal developments. The drafter will try to foresee the future, and allow for it in the wording.’
