An arbitration which is not administered by an institution under its rules is an ad hoc arbitration and is the preferred option in certain sectors.
An arbitration clause in a contract may provide for arbitration in London without specifying an institution to administer the proceedings under its rules. If so, this will be an “ad hoc” arbitration, which will be conducted under the Arbitration Act 1996 with the Commercial Court in a supporting role. See my blog post, Ad hoc arbitration: a quiet majority.
It is open to the parties to an ad hoc arbitration to agree on a set of procedural rules to govern their arbitration.
Ad hoc arbitrations arising from disputes in the shipping industry will often be submitted to arbitrators in London who accept appointments on the London Maritime Arbitrators Association (LMAA) Terms. I am an Aspiring Full Member of the LMAA and will accept appointments on its Terms: lmaa.london/arbitrators-aspiring-full-members/.
Parties may also choose an institution as an “appointing authority” whether pursuant to the UNCITRAL Arbitration Rules or otherwise. It is then the institution, not the courts, which could:
In London, the LCIA (see below) is frequently appointed to carry out such functions in ad hoc arbitrations, sometimes on the recommendation of an arbitral tribunal after it has been appointed: www.lcia.org/Dispute_Resolution_Services/LCIA_Services_in_adhoc_proceedings.aspx
Having served as Registrar of the LCIA for four years, I am familiar with the services it provides to parties in ad hoc arbitrations.
An arbitration clause may, instead, provide that the parties’ dispute will be submitted to an institution for determination under its own rules. In addition to all of the functions of an appointing authority listed above, the institution should:
Users of institutional arbitration are sometimes unaware of the extent to which ad hoc arbitration is preferred in certain sectors, such as shipping. See my blog post on silos in arbitration: blogs.lexisnexis.co.uk/dr/the-silo-effect-in-arbitration/
Caseload statistics from institutions sometimes mask the fact that they include filings which don’t reach the desks of arbitrators. Ad hoc arbitrations, on the other hand, generally commence with the appointment of an arbitrator. See my Lexis Blog post Arbitrations without arbitrators: an institutional paradox.
Commercial parties deserve choice. It is essential that ad hoc and institutional arbitration be allowed to thrive and develop alongside each other. Regrettably, ad hoc arbitration finds itself increasingly under attack by governments, university law schools, the media, and others. Unjustified claims are made for institutions' superiority and thought leadership.
In a joint article with Cherine Foty, Conflicting Perceptions of Ethics in International Arbitration, Arbitration, 85, 2 (2019), pp 185-2020 (download here), we challenged the notion that arbitral institutions are uniquely suited to uphold standards of conduct and ensure fairness in arbitrations. Arbitrators who handle ad hoc arbitrations, associations of arbitrators, such as the LMAA, and professional bodies, such as the CIArb, are just as well suited to fulfil these functions.
See also my ICMA XXI paper, Ad hoc arbitration and its enemies, in which I called for the international commercial arbitration community to demonstrate solidarity and ensure that the voice of ad hoc arbitration was heard.
