Says who? The High Court in London, no less.As yet, there are no further details (this news appeared just minutes ago)
Obviously the law in question, whatever it is, needs to be changed. Hopefully that'll be the next step, because this decision is not acceptable. It's our country, and we'll decide, via our elected government!
Now, admittedly, today's decision affects only the temporary cap between now and when the official cap takes effect from next year; but in the meantime there is bound to be a rush "to beat the cap". This really is very silly, and is of no positive benfit to anyone - or at least, not to anyone interested in the welfare of our country.
