Career and publications
Between 2005 and 2007 Parish worked as head of legal department for the Brcko Final Award Office of the High Representative for Bosnia and Herzegovina (OHR). Shortly after leaving Bosnia in 2007, Parish wrote "The Demise of the Dayton Protectorate", which was later used to argue for closure of the OHR. He then moved to Geneva, where he worked in different law firms and held positions as visiting lecturer and Honorary Professor in various universities.
Parish's book on reconstruction in post-war Brcko, A Free City in the Balkans (2009), has attracted domestic and international attention. The book has been criticized for being too sceptical of the international community's statebuilding efforts in the country.
In 2010 Parish wrote a commentary on the 22 July 2010 decision of the International Court of Justice declaring Kosovo's unilateral declaration of independence to be lawful. He expresses the view that while Kosovo's independence was inevitable, judicial determination of the issue was unsatisfactory as a matter of policy.
Parish's book Mirages of International Justice (2011)  advances a constructivist account of international law. He thinks sovereign states would never agree to create genuinely impartial and independent international courts that would enforce international law against themselves. Thus international courts are deliberately made powerless, and they occupy precarious roles in the balance of power in which they are liable to make decisions in accordance with Great Power interests. International tribunals proliferate not because states want to see international justice done but because they want to associate themselves with the ideals captured in discourse about international law without making any real commitments. The world of international relations remains an anarchy, but international courts (and indeed international organizations in general) are part of an illusion that the world is ordered in accordance with moral principles. Nevertheless, Parish is a defender of controversial investment treaty arbitration, a system of international law that allows investors to sue states.
Parish spoke to the UN General Assembly in April 2013 in a meeting organized by its then President Vuk Jeremic. He chaired a debate about the effectiveness of international criminal justice, and how it might be made more efficient and improved. Parish was a key supporter of and Chief International Political Advisor to Jeremic in his campaign to become elected UN Secretary General in 2016, and his firm, Gentium Law Group, was reported as a principal supporter Jeremic, who came in second behind António Guterres.
Parish has given evidence to both the European Parliament and the House Committee on Foreign Affairs of the US Congress in 2016 on issues relating to international organizations and international law. He is an advocate of free trade and open-market economics, and says that international investment is a consequence of free trade.
Parish is a scholar of the jurisprudence of both the International Criminal Tribunal for the Former Yugoslavia and international criminal law in general.
Since 2014 Parish has been the managing partner of Gentium Law Group, a small international arbitration firm headquartered in Geneva, Switzerland. He is reported as having represented a number of governments, including Turkey, Tajikistan and Gulf monarchies, as well as commodities-trading companies in their litigation interests. Gentium was one of the first in a new breed of "boutique" arbitration law firms that involves teams of senior arbitration lawyers splitting away from large established law firms and forming their own smaller practices under new brands. Although the departure of Holman Fenwick's team was known to be extraordinarily acrimonious, Gentium seems to have thrived, while the Geneva office of the law firm from which it departed fared less well. The group was the first firm to be nominated as a Global Arbitration Review Top 100 Law Firm worldwide within the first year of its operation. The Gentium Law Group, has been named by Global Arbitration Review in consecutive years as one of the top one hundred law firms worldwide in its field.
In 2013 and 2018 Parish was named as one of the three hundred most influential people in Switzerland. Parish has also been named as Dispute Resolution Lawyer of the Year in Switzerland, 2018.
Parish was arrested on 29 May 2018 then released by order of the Geneva public prosecutor's office. He is being investigated for defamation, attempted extortion, attempted coercion, contempt of official orders and breach of professional secrecy. He was detained for three weeks. The complaint was from two Russian oil traders. who said that he used false allegations to blackmail them into paying a grossly inflated legal bill. The Swiss newspaper Le Temps reported in September 2016 that Parish and two unnamed lawyers in Geneva are being investigated on suspicion of forgery, along with one of Parish's clients. The lawyers are suspected of participating in a sham arbitration relating to alleged corruption. The sham award was allegedly submitted to the English courts for enforcement.
