Courts, parliaments and independent media limit executive power in different ways: courts test government action against law, parliaments question and investigate ministers, and media bring government conduct into public view. They are complementary checks, not interchangeable branches—and how much authority each has depends on the country’s constitutional system.
How courts limit executive power
Courts can review whether government decisions comply with the constitution and other laws. Depending on the legal system, a court may be able to set aside unlawful action, require a public authority to act lawfully, or provide a remedy when rights have been infringed. The scope of review and available remedies vary by jurisdiction; courts do not have identical powers everywhere.

South Africa offers a specific constitutional example. Section 165 of its Constitution says: “The courts are independent and subject only to the Constitution and the law, which they must apply impartially and without fear, favour or prejudice.” It also prohibits interference with the functioning of the courts. Sections 167 and 172 set out the Constitutional Court’s role in specified constitutional matters and the powers courts may exercise when deciding constitutional disputes. South African Constitution, Chapter 8.
South Africa’s Parliament describes courts as a way for individuals and groups to test and enforce their rights. That access matters: a legal limit is useful only if a person or organization can bring a claim and a court can decide it. Parliament of South Africa: What Parliament Does.

How Parliament holds the government to account
Parliamentary scrutiny is political and public as well as legal. In the UK, Parliament identifies questions to ministers, debates and committee investigations as principal ways members examine government action. Ministers may be required to explain and defend policies and decisions publicly. UK Parliament: Government and Parliament.
- Questions give members a way to ask ministers about decisions, implementation and government performance.
- Debates put disagreements and policy choices on the public record.
- Committee investigations allow more focused examination of government activity and evidence.
These mechanisms do not guarantee effective oversight. A legislature’s practical ability to scrutinize an executive depends on its powers, access to information, time, expertise and willingness to investigate. The UK examples describe scrutiny methods, not a universal set of parliamentary powers.
Rank #2
Why independent media matter
Independent media help limit executive power by making government conduct visible to the public. Reporting can surface decisions, claims and problems that might otherwise receive little attention, giving citizens and legislators information with which to question those in power. Media are not a formal branch of government: their checking role depends on editorial freedom rather than constitutional authority to issue binding decisions.
The Council of Europe says editorial decisions should not be influenced by governments, regulators, commercial interests or media owners. It also says media should not be prevented from covering contentious issues, including corruption. These principles describe conditions for editorial independence; they do not establish that every country protects media freedom in the same way. Council of Europe: Media pluralism and diversity.
Rank #3
How the checks work together—and where they can fall short
The three mechanisms can reinforce one another. Media reporting may bring an issue to public attention; parliamentarians may then question ministers or investigate it; and people affected by government action may seek a legal remedy in court. That sequence is possible, not automatic: each institution has a distinct role, and no one mechanism substitutes for the others.
- Courts depend on independence, access to review and respect for their decisions. Their authority is bounded by the law and the remedies available in that jurisdiction.
- Parliaments need the powers and practical capacity to obtain information and scrutinize the executive.
- Media need editorial freedom from government, regulatory, commercial and ownership pressure to report on matters of public concern.
A UK government speech by the Lord Chancellor described judicial review as “a vital check on unbridled power” and called for preserving a balance between Parliament and the courts. That is the speaker’s view in a UK government speech, not a universal rule about how the relationship must work. UK Government: Lord Chancellor speech at the University of Law.

Constitutional design shapes what each institution can do. Comparing systems means looking at the legal scope and remedies of judicial review, the powers and practical capacity of legislatures to investigate or obtain information, and the legal, political and ownership conditions that protect editorial independence. The examples here illustrate particular arrangements in South Africa and the UK; they do not support a current global ranking of how effectively countries limit executive power.
