§ 111. Mr. Biggs-Davison
asked the Secretary of State for the Home Department what guidance and criteria are given to the Metropolitan Police in determining when a vehicle is, or is not, causing an obstruction.
§ Mr. R. A. Butler
The question of what constitutes an obstruction is one of law, and falls to be determined by the courts. The Commissioner of Police is responsible for enforcing the law and the instructions he issues, in this as in other operational matters, are confidential.
