Jonathan frequently handles regulatory disputes on behalf of commercial clients. In transport, he handles detailed and often complicated responses to Call Letters by Traffic Commissioners seeking to suspend, curtail or revoke Operator Licences for vehicle defects, inspection interval irregularities, drivers hours and tachograph offences.

Jonathan deals with Trading Standards and local authorities over for example, online event ticketing mis-selling, transparent and fair-pricing, outstanding recall vehicle issues and product safety regulations, mis-labelling, noise and pollution abatement notices.

In 2019, Jonathan forced the CTSI to launch a public consultation over its planned publication of new guidance to dealers over the sale and supply of used cars.

Jonathan also spearheaded the successful Crown Court appeal under the Consumer Protection from Unfair Trading Regulations 2008 in a case which attracted nationwide media attention, of Middlesbrough Borough Council -v- Pendragon PLC, reversing the first instance decision which sought to uphold the ASA’s flawed interpretation and application of the law on used-vehicles and the disclosure of ex-rental vehicle status to consumers in Glyn Hopkin and Fiat Chrysler.
