Practice notes

This Practice Note

This Practice Note supports commercial practitioners advising merchants or their subcontractors. It outlines the Payment Card Industry Data Security Standards (pci DSS), traces the origins of PCI DSS and the Payment Card Industry Security Standards Council (PCI SSC), sets out who is in scope, and distils its principles and requirements. It reviews compliance obligations and enforcement, including card scheme penalties, and how these align with UK privacy and data security laws and standards. Topics addressed include PIN Transaction Security (PTS), the Payment Application Data Security Standard (PA-DSS), tokenisation, and considerations for shared-hosting providers. It also highlights key contractual protections that merchants should obtain from service providers. The Note excludes sector-specific laws, practices, or PCI DSS duties relevant to financial institutions, merchant acquirers, payment processors, payment networks, and banks, as these are for specialists.

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...
