Patrick Green QC

"Hugely bright, immensely enthusiastic and utterly charming …" "… a lateral, strategic and outside-the-box thinker who works well with instructing solicitors."

Chambers UK 2020


Patrick Green regularly appears in the Supreme Court, Court of Appeal and the High Court in a variety of cases, spanning commercial law and civil fraud, EU, investment treaty arbitration, judicial review, employee patent compensation, tax and, occasionally, employment and levy law.

Notable appearances in the Supreme Court include:

  • R (Miller & Others) v Secretary of State for Exiting the European Union [2017] UKSC 6 − the ‘Gina Miller’ case concerning whether legislation or Parliamentary consent was required for the government to notify under Art.50.
  • Micula v Romania UKSC 2018/0177 − as to the right to enforce an ICSID arbitration award said (by the EU Commission) to conflict with State aid rules and whether the UK is bound under EU law to put itself in breach of prior international obligations under the ICSID Convention.
  • Shanks v Unilever PLC & Others [2019] UKSC 45 an employee patent compensation case, as to whether or not Unilever’s size is such that a benefit from patent licensing of more than £20 million is therefore not ‘an outstanding benefit’ entitling the inventor of the leading diabetic home testing technology to any compensation.

He has been an accredited mediator since 1997 and co-founded the mediation organisation ResoLex, based at the IDRC in Fleet Street. He continues to lecture at the LSE and internationally on mediation and negotiation where he was a Visiting Fellow between 2005 and 2012.
