Uganda Law Society and Military Trial Limits

Attorney General v Uganda Law Society, Constitutional Appeal 1 of 2006, [2009] UGSC 2, is a major Supreme Court decision on fair trial, military jurisdiction and public interest constitutional litigation in Uganda. It arose from events that were both legal and political. Armed security agents interfered with the implementation of bail granted by the High Court to Dr Kizza Besigye and other accused persons. The accused were then taken before the General Court Martial and charged with offences that overlapped with proceedings already before the ordinary courts. The Uganda Law Society challenged the situation, and the case became a landmark on the constitutional limits of using military processes alongside civilian criminal justice.

The Supreme Court sat at Mengo. The bench included Odoki CJ, Tsekooko JSC, Mulenga JSC, Kanyeihamba JSC, Katureebe JSC, Ogoola Ag JSC and Kitumba Ag JSC. Mulenga JSC wrote the leading judgment, and the other members of the Court agreed with his reasoning and conclusion. The decision carries strong precedent value because the Court did not treat the matter as a narrow procedural quarrel. It treated jurisdiction, judicial authority, fair hearing and obedience to court orders as constitutional questions at the centre of the rule of law.

The facts need to be remembered in concrete terms. The accused persons were before the High Court in criminal proceedings. They applied for bail, and the High Court granted it. Before they could be released, armed security agents entered the court premises and interfered with the release process. Soon afterwards, the accused persons were brought before the General Court Martial and charged with terrorism and unlawful possession of firearms. The Uganda Law Society then brought a public interest petition against the Attorney General, arguing that these actions violated the Constitution. The petition challenged not only the behaviour of security agents but also the attempt to subject the accused to parallel military proceedings.

The case may be read as a dispute about one group of accused persons, but it is wider than that. It asks whether the State can move an accused person from the ordinary courts into a military forum when ordinary judicial orders become inconvenient. It also asks whether several proceedings arising from the same facts can be used to intensify pressure on an accused person. In a constitutional democracy, those questions are not technical. They go to whether courts control criminal process or whether executive force can overtake it.

The Supreme Court dismissed the Attorney General’s appeal and allowed the Uganda Law Society’s cross appeal. In practical terms, it upheld the view that the military proceedings were unconstitutional in the circumstances. The Court’s reasoning was built around a simple but powerful idea: a fair trial cannot take place before a body that lacks lawful jurisdiction. A tribunal does not become competent merely because it uses legal language or sits in a courtroom style setting. It must have authority over both the person and the subject matter.

That point was decisive for the General Court Martial. The terrorism charge was brought under the Anti Terrorism Act, which placed jurisdiction over serious terrorism offences in the High Court. The Supreme Court reasoned that an offence under a law other than the UPDF Act could fall within military jurisdiction only where the accused person was properly subject to military law. The charge sheet did not establish that necessary link. Without it, the offence could not simply be transformed into a service offence. Jurisdiction cannot be created by assertion, and it cannot be cured by the State’s preference for a particular forum.

The Court also explained that a trial before an incompetent court is a nullity from the beginning. This is one of the most important statements in the case. It means that fair trial is not limited to whether the accused is allowed to speak, call witnesses or cross examine. Those matters are important, but they come after the prior question of competence. If the forum has no lawful power to try the case, then the entire process is defective. A person cannot receive a constitutionally fair trial in a court that should not be trying him at all.

The decision also dealt with concurrent proceedings. The Attorney General argued for a narrow view of Article 28(9), which protects against being tried again after conviction or acquittal. On that view, the protection would apply only after a full trial had already ended. The Supreme Court preferred a broader and more purposive approach. It treated the risk of multiple proceedings arising from the same facts as part of the wider fair hearing problem. The danger was not only technical double jeopardy in the final sense. It was the practical unfairness of exposing accused persons to overlapping processes, possibly leading to multiple punishments for the same basic conduct.

This part of the judgment may suggest that constitutional rights should be read for their protective purpose, not only their narrow literal phrasing. A person who is being pulled between the High Court and a military court over the same alleged conduct faces a real burden. Lawyers must prepare in two places. Bail in one forum may be undermined by detention through another. The accused may feel that no court order is final because a different arm of the State can restart the process elsewhere. The Supreme Court’s approach recognises that fair trial includes protection from oppressive prosecution strategies.

The invasion of the High Court premises gave the case an institutional dimension. Court orders are not advice. They are commands of law unless stayed, varied or overturned by a competent court. If security agencies can physically block the release of accused persons after bail has been granted, judicial authority is weakened in public view. The Supreme Court’s decision therefore protects both individual liberty and the dignity of courts. It says, in effect, that the State must challenge court orders through law, not through force.

There is also an important lesson about public interest litigation. The Uganda Law Society was not merely defending one client’s private claim. It was acting as a professional body concerned with the administration of justice. The Court’s willingness to entertain the petition shows that constitutional litigation may be necessary where state action threatens the legal system itself. In that sense, the case is useful for bar associations, civil society groups and public interest lawyers. It shows that institutional harm to the rule of law can justify constitutional proceedings even where named individuals are the immediate victims.

The judgment also discusses precedent. It criticised the attempt by the Constitutional Court to depart from earlier authority without a lawful basis. The Court’s concern was not formalism for its own sake. If courts of the same level freely disregard earlier decisions, legal certainty suffers. People cannot plan litigation, prosecutors cannot know the proper forum, and judges may produce conflicting rules on basic constitutional questions. The doctrine of stare decisis therefore supports stability, while still allowing departure where a decision is distinguishable, overruled by a higher court or truly made in error in a recognised legal sense.

A fair critique is that cases involving military jurisdiction often arise in politically charged situations, and courts may face intense pressure. The judgment is strong, but later events in Uganda have shown that the boundary between military and civilian justice has remained contested. That does not weaken the precedent. If anything, it makes the case more important. A rule that is repeatedly tested is not useless. It is often the rule that lawyers must keep returning to.

For prosecutors and security agencies, the practical lesson is direct. Choose a lawful forum from the start. Do not use the General Court Martial as a substitute for the High Court where the law gives jurisdiction to civilian courts. Do not create parallel proceedings as a way of avoiding bail, increasing pressure or bypassing ordinary safeguards. For defence lawyers, the case supplies a clear argument: before addressing the merits of a military charge, ask whether the accused is subject to military law and whether the alleged offence properly falls within military jurisdiction.

The case continues to matter in later military justice debates. A later Supreme Court decision in Attorney General v Kabaziguruka, delivered in 2025, also considered military courts, civilians and fair hearing. The continued relevance of Attorney General v Uganda Law Society shows that the 2009 decision remains part of Uganda’s constitutional foundation on military jurisdiction. It is particularly useful where the State seeks to treat military convenience as a reason to move cases out of ordinary courts.

The lasting value of Attorney General v Uganda Law Society is its insistence that fair trial begins with lawful jurisdiction and respect for court authority. The case does not deny that military courts may have a role in military discipline. It says that the role must remain within constitutional and statutory limits. It also says that accused persons should not be exposed to overlapping proceedings based on the same facts in a way that undermines fairness. In a legal system where security concerns and criminal prosecution can easily overlap, that message remains both practical and necessary.
