Location of Sovereignty in the UK
Legal and Political Sovereignty

Where sovereignty now lies

Distinction between legal & political sovereignty

Legal sovereignty

means ultimate legal power

Political sovereignty

refers to where power lies in reality

no other body/institution can overrule Parliament (has legal sovereignty)

courts will only enforce laws passed by the UK Parliament and will only uphold powers granted by the UK Parliament

although we know the UK Parliament is legally sovereign, we have to understand that real power may lie elsewhere
= called political sovereignty

Key Term(s)

Legal sovereignty:

  • ultimate legal power
  • is no higher political authority
  • legal sovereignty cannot be set aside by any other body or by constitutional rules

Omnicompetent:

  • a description of the UK Parliament stating that it is able to take any action and pass any law it wishes
  • are no constitutional restraints on what the UK Parliament can do

Changing location of sovereignty

one aspect location of legal sovereignty in the UK has changed: all the sovereignty shared or passed to the EU since 1973 (when the UK joined) has been returned since 2021

location of political sovereignty has changed in many ways:

political sovereignty has moved to the devolved administrations

some of the political sovereignty of the executive is shifting towards the UK Parliament


= is particularly true in the areas of foreign interventions and negotiation of foreign treaties

increasing use of referendums has transferred political sovereignty to the people

Prime Minister has lost control over the date of general elections under the Fixed Term Parliaments Act

Human Rights Act shifted control over the enforcement of rights from the UK Parliament to the Supreme Court

remains true that UK Parliament is legally sovereign


= ultimately, Parliament is omni-competent and can determine how power is distributed in the UK

HOWEVER, if we look at sovereignty in a broader sense (i.e: political sovereignty) the location of sovereignty depends on the following circumstances:

in a referendum, the people are sovereign despite (technically) the result of a referendum is not binding on Parliament

at a GE, the people are sovereign as they determine who shall exercise power for the next 5 years

for issues that are part of the government’s electoral mandate, it can be said that the government is sovereign as it has popular consent for what it is doing

with devolved issues, the devolved administrations are effectively sovereign as it is unthinkable that they would be overruled by the UK Parliament

when implementing the ECHR, the Supreme Court becomes sovereign
