Security Service Act 1989

Enforcement

No single statutory enforcer

Status

In Force

Penalty ceiling

Regulated

The Security Service Act 1989 places MI5 on a statutory footing, creates the post of Director General, and establishes the Intelligence Services Commissioner oversight function. It has no business-facing regulatory content and creates no obligations on private businesses or individuals. The Act is a constitutional statute governing a government intelligence service and is not the kind of legislation cited in business compliance guides; enforcement (via the Investigatory Powers Tribunal) is not business-facing.
