Extradition CASES

In English law, extradition is the formal process by which one state surrenders a person to another state to face criminal trial or serve a sentence. It is governed by treaties, international agreements, and domestic legislation.

Definition and Principles

Extradition balances international cooperation in criminal justice with safeguards to protect individual rights. It ensures alleged offenders cannot evade justice by crossing borders.

Requirements for Establishing

  • Legal framework: Extradition must be authorised by statute or treaty, such as the Extradition Act 2003.
  • Extraditable offence: The conduct must amount to a criminal offence in both jurisdictions.
  • Judicial oversight: UK courts review requests to ensure legal and human rights compliance.
  • Safeguards: Protection against double jeopardy, political prosecutions, or inhuman treatment is essential.

Practical Applications

Extradition applies to offences ranging from financial crime to terrorism. It facilitates cooperation with both EU states under the European Arrest Warrant system (before Brexit) and with other countries worldwide.

Importance

Extradition underpins international law enforcement by preventing safe havens for criminals, while ensuring due process and protection of fundamental rights.
