Para 49 NPPF
“relevant policies for the supply of housing should not be considered up-to-date if the local planning authority cannot demonstrate a five-year supply of deliverable housing sites”.
What is the object of this sentence? What was ‘for the supply of housing’ supposed to add to its meaning? Did it add anything? If it was supposed to mean anything why not rewrite it plain English not in strangulated grammer with a passive tense, uncertain object and double negative.
