Bonham’s Case (1610): Parliament Above the Law, or Law Above Parliament?

“Can an Act of Parliament be nullified by a court?” — Bonham’s Case poses one of the most controversial questions about the scope of Parliament’s power and the limits of law in UK constitutional history.

Hello! Today I’m diving into Bonham’s Case (1610). Studying this case made me wonder: “Is the law-making Parliament truly above the law? Or does the law itself embody higher principles that even Parliament must obey?” This dispute, which began over a physician’s licence, still resonates as a landmark in discussions of constitutionalism and the rule of law.

Background

Bonham’s Case arose from a dispute between Thomas Bonham, a physician practising in London, and the Royal College of Physicians. The College regulated medical qualifications and could prohibit unlicensed practice. Although Bonham held a Cambridge degree, he lacked a London licence, was fined by the College, and even imprisoned. He sued, taking the dispute to court.

Key Legal Issues

At the heart of the case was the question: “Can a court invalidate an Act of Parliament?” Bonham argued that the statute used to punish him was unfair and unconstitutional.

Issue	Explanation
Recognition of Qualification	Could Bonham, with a Cambridge degree, be recognised to practise in London?
Judicial Power	Do courts have authority to declare an Act of Parliament void if contrary to fundamental principles?
Conflict of Interest	Was it legitimate for the Royal College to fine in a way that benefited itself?

The Court’s Decision

Sir Edward Coke, the presiding judge, made a historic statement. He suggested that “even Acts of Parliament may be controlled by the common law” when they offend common right and reason. Key points:

• No one should be a judge in their own cause; a statute that is unreasonable or repugnant can be treated as void.
• The College acting as prosecutor, judge, and a beneficiary undermined fairness.
• Bonham’s punishment was improper, and the court could restrict the College’s asserted powers.

Constitutional Significance

Bonham’s Case is often seen as planting seeds of the rule of law in English constitutional thought. Coke’s remarks challenged absolute parliamentary authority and hinted that law embodies higher principles. Ironically, the case influenced the United States more than the UK: when the U.S. Supreme Court established judicial review in Marbury v. Madison (1803), Bonham’s Case served as a historical touchstone.

Impact & Significance

The case sparked enduring debates about the relationship between Parliament and the courts. Unlike the traditional doctrine of absolute parliamentary sovereignty, Bonham’s Case suggested that courts might limit Acts of Parliament. Key impacts:

Impact	Details
Idea of Judicial Review	Regarded as an early source for the notion that courts can constrain Acts of Parliament.
Influence on U.S. Constitutional Law	Indirectly shaped the development of judicial review in the U.S.
Controversy in the UK	Clashes with the doctrine of parliamentary sovereignty; remains debated in scholarship and practice.

Contemporary Meaning

Today, Bonham’s Case is sometimes called the “English Marbury v. Madison,” though in modern UK law parliamentary sovereignty prevails, limiting its direct legal force. Still, it poses a vital philosophical question: “Can law stand above the lawmakers?” Contemporary significance includes:

• A foundational case for debates on the rule of law and constitutionalism.
• Significant influence on constitutional development beyond the UK, notably in the U.S.
• Frequently cited in balancing parliamentary sovereignty with overarching constitutional principles.

Frequently Asked Questions (FAQ)

Q What was Bonham’s Case about?

A 1610 dispute in which physician Thomas Bonham challenged the Royal College of Physicians’ sanctions, raising the question whether courts could constrain Acts of Parliament.

Q Who delivered the judgment?

Sir Edward Coke, then Chief Justice of the Court of Common Pleas.

Q What was Coke’s key statement?

That in some cases the common law controls Acts of Parliament — laws contrary to common right and reason may be treated as void.

Q How did it affect American law?

It served as a historical reference for the U.S. Supreme Court’s establishment of judicial review in Marbury v. Madison (1803).

Q How is it viewed in the UK?

Given the dominance of parliamentary sovereignty, its direct legal force is limited, though it remains significant in academic debate.

Q What question does the case pose today?

Whether the lawmakers themselves can be constrained by higher legal principles — a core question of the rule of law and constitutionalism.

Conclusion

Bonham’s Case (1610) shows how much debate and experimentation it took for “the rule of law” to become a lived reality. When I first read Coke’s lines, they felt far too prescient to dismiss as rhetoric. Though the UK ultimately prioritised parliamentary sovereignty, the notion that “law constrains the lawmaker” travelled across the Atlantic and became a constitutional cornerstone. What do you think?
