"It is unlawful for a person, in the case of a woman employed by him at an establishment in Great Britain, to discriminate against her - (a) in the way he affords her access to opportunities for promotion, transfer or training, or to any other benefits, facilities or services, or by refusing or deliberately omitting to afford her access to them, or (b) by dismissing her, or subjecting her to any other detriment."

"A constable, therefore, when acting as a peace officer, is not exercising a delegated authority, but an original authority, and the general law of agency has no application."
"Where the exercise of a discretionary power is entrusted to a named officer - eg a chief officer of police, a medical officer of health or an inspector - another officer cannot exercise his powers in his stead unless express statutory provision has been made for the appointment of a deputy or unless in the circumstances the administrative convenience of allowing a deputy or other subordinate to act as an authorised agent very clearly outweighs the desirability of maintaining the principle that the officer designated by statute should act personally."
