Arbitration rules definition

What does Arbitration rules mean? arbitration rules are the procedural framework that governs how an arbitration is run, including commencement, appointment and challenge of arbitrators, case management, evidence, confidentiality, hearings, interim (and often emergency) relief, awards and costs.

UNCITRAL Expedited Arbitration Rules: Scope, Procedures and Practical Guidance for Ad Hoc Arbitrations

Published by a LexisNexis Arbitration expert

Practice notes

This Practice Note reviews and offers guidance on The United Nations Commission on International Trade Law (UNCITRAL) Expedited Arbitration rules for ad hoc arbitrations, which came into effect on 19 September 2021 (the Expedited Rules).

Cutting the duration and expense of arbitral processes remains a persistent theme within the arbitration community and a regular subject of debate.

Some arbitration users have voiced concerns that cases are overly long, costly and excessively formal, particularly where Disputes are simpler or of modest value in practice.

Tomlin orders in England and Wales: CPR guidance on drafting, confidentiality, approval, variation, enforcement, limitation, CCA issues, court-specific requirements, sample wording and precedents

This Practice Note This Practice Note reviews mechanisms used in settling litigation. A Tomlin order consists of a consent order paired with a schedule. It operates to stay proceedings on terms that have been agreed. The provisions contained in the schedule may remain confidential. This Practice Note describes the scope of confidentiality attaching to the schedule and sets out how it differs from a standard consent order. Sample wording for a Tomlin order is included, alongside links to precedents, as well as guidance on court approval. It also addresses varying, setting aside and enforcing a Tomlin order, including the considerations the court will take into account when handling applications for each. Further guidance is provided on interpreting and applying the relevant provisions of the CPR; however, some courts and divisions impose very specific requirements for both drafting and approval, and for approaching the schedule and confidentiality issues. Accordingly, you must consider the particular rules and court guide provisions in the forum where your claim is proceeding when drawing up the Tomlin order...
