Mazur: When Regulators Make Simple Things Complicated

Why It Matters

The judgment restores the legal sector’s traditional delegation model while imposing a clear, enforceable duty of genuine supervision, reducing compliance risk and criminal liability for firms.

Key Takeaways

• Court of Appeal allows non‑authorised staff to perform litigation under supervision
• SRA and Law Society’s earlier interpretation deemed legally incorrect
• Genuine supervision now a criminal offence if inadequate under LSA
• Firms must audit and document delegation policies immediately
• High‑volume claims firms face heightened scrutiny of supervision ratios

Pulse Analysis

The Mazur case has become a watershed moment for the UK legal services market. After the High Court’s September ruling forced firms to treat non‑authorised staff as barred from conducting litigation, the Court of Appeal’s March decision re‑affirmed long‑standing delegation practices, provided they are backed by genuine supervision. This reversal not only rescues law centres and claims firms from operational paralysis but also underscores the importance of interpreting the Legal Services Act 2007 in line with industry realities rather than theoretical constructs.

Regulators misstepped by persuading the High Court that the absence of an explicit exemption in Schedule 3 meant non‑authorised personnel could only assist, not act. The appellate judgment rejected that inference, emphasizing that each reserved activity carries its own history and that the SRA’s existing effective supervision guidance already covered the ground. Consequently, inadequate supervision is now a criminal offence under the LSA, raising the stakes for compliance teams and prompting an imminent overhaul of SRA guidance.

Practically, firms must act swiftly: re‑read the SRA’s supervision guidance, audit current delegation arrangements, and create living records of authorised versus non‑authorised staff. High‑volume claims operations should especially scrutinise supervisor‑to‑team ratios and consider formal sign‑off procedures for court documents. By embedding robust, documented oversight into daily workflows, firms can turn supervision from a background compliance checkbox into a frontline legal safeguard, ensuring resilience against future regulatory challenges.
