II. Facts (Brief Summary): The government, exercising its prerogative powers, banned trade unions at GCHQ without prior consultation, a practice that had previously been followed.

This case, Council of Civil Service Unions v Minister for the Civil Service (often abbreviated to GCHQ), is a landmark case concerning the limits of judicial review in the face of national security concerns.
I. Core Issue: The case centers on whether the government's decision to ban trade union activities at GCHQ (Government Communications Headquarters) was lawful, even though it breached a long-standing practice of consultation with employees.
II. Facts (Brief Summary): The government, exercising its prerogative powers, banned trade unions at GCHQ without prior consultation, a practice that had previously been followed.
III. Legal Arguments & Decision:
- Legitimate Expectation: The unions argued they had a legitimate expectation of consultation, based on the established practice of the government. This legitimate expectation, while not a legal right, is a concept that enables judicial review when a public body departs from promised or established procedures. The House of Lords agreed that such an expectation existed.
- National Security Exception: The government defended its actions on grounds of national security. The House of Lords accepted that national security could justify overriding a legitimate expectation. However, the key development here is that the court required evidence to support the national security claim. Simply asserting "national security" was no longer sufficient.
- Justiciability of Prerogative Powers: The case affirmed that the courts can review the exercise of prerogative powers, even those related to national security, provided there is sufficient evidence to support the decision.
- Shift in Judicial Approach to National Security: Before GCHQ, claims of national security were largely accepted without scrutiny by the courts. This case established a new precedent: courts will now examine claims of national security to determine whether they are genuinely based on evidence.
- Legitimate Expectation Doctrine Reinforced: The case reinforces the importance of the legitimate expectation doctrine, demonstrating that established government practices can give rise to reviewable expectations, even in the absence of an explicit promise.
- Limitations on Prerogative Powers: The case shows that even prerogative powers are not entirely immune from judicial review. There are limits, particularly where national security is concerned, but these limits require demonstrable justification.
- Define "legitimate expectation" in the context of administrative law. How did it apply in GCHQ?
- Explain the pre-GCHQ and post-GCHQ approaches to judicial review of decisions based on national security. What was the crucial change?
- Why was the justiciability of prerogative powers a significant aspect of this case?
- What evidence would be considered sufficient to justify overriding a legitimate expectation based on national security?
- How might this case influence future challenges to government decisions that affect the public?
