Copyright © 2025 LexisNexis

What is institutional arbitration?

This Practice Note introduces what it means for a dispute to be referred to arbitration under a set of institutional rules. It gives details of the main institutional arbitration bodies and links to bespoke content about them. The note also discusses when institutional arbitration would be appropriate and sets out the advantages and disadvantages of arbitrating under institutional rules.

See Practice Note: Institutional arbitration—an introduction to the key features of institutional arbitration

What is ad hoc arbitration?

This Practice Note gives information about arbitrations that are conducted without the supervision of an arbitral institution, known as ad hoc arbitration. Arbitration under national legislation such as the Arbitration Act 1996 (AA 1996), or under the UNCITRAL Rules which are not administered by an institution would fall into this category. The note sets out the advantages and disadvantages of choosing ad hoc arbitration and gives a precedent ad hoc arbitration clause that may be used as an arbitration agreement.

Stay of application for injunction in favour of Arbitration (Hunt v IPS Law LLP and Others)

Arbitration analysis: The claimant, Mr Hunt, invested £1.05m in January 2023 through IPS Law LLP (‘IPS Law’), the second defendant, which was meant to hold the funds for the first defendant, Oceania Capital Reserves Ltd (‘Oceania’). IPS Law later apparently transferred the funds, but the circumstances in which that occurred (and the instructions on which IPS Law and its principal, Mr Farnell, the third defendant, relied) were unclear. Mr Hunt applied for an injunction to preserve the funds in IPS Law’s account. The defendants, in return, applied for a stay of the proceedings, arguing that the Investment Agreement between Mr Hunt and Oceania (with IPS Law as the ‘Investment Escrow Party’) referred disputes to arbitration. The court held that IPS Law was not a party to the arbitration clause and could not rely upon it under the Contracts (Rights of Third Parties) Act 1999 (C(RTP)A 1999) (Mr Farnell accepted he was not a party). The court decided, however, that there was a serious issue to be tried in relation to the handling of Mr Hunt’s funds and accordingly granted a proprietary injunction. The case addresses issues over the court’s jurisdiction to order a stay under section 9 of the Arbitration Act 1996 (AA 1996) and its ability to order relief where funds held in a solicitors’ client account have been paid away apparently without instruction.

Court of Appeal—final anti-suit injunction varied to avoid Russian court penalty (UniCredit v RusChemAlliance)

Dispute Resolution analysis: The Court of Appeal ordered that a final anti-suit injunction (ASI) should be varied to remove the injunctive element but maintain a declaration that the English court has jurisdiction to hear the claim. The applicant bank (UniCredit) would otherwise have incurred a significant penalty from the Russian court. The original ASI had prevented the respondent (RCA) (who had breached the Paris-seated arbitration clause) from bringing proceedings in Russia. The court confirmed that CPR 3.1 (the court’s general powers of management) and CPR 52.30 (reopening of final appeals) provide the court with powers to vary or revoke an ASI, if the commercial situation allows. There is no material distinction between where the order is an interim vs a final order and a pragmatic approach will be afforded when considering factors related to the application, namely (i) if the applicant has been coerced, (ii) English public policy and (iii) the impact if the application is not granted.
