News Written by

Leading energy and resources lawyer Darren Grondal has joined Johnson Winter & Slattery as a consultant. Darren joined the firm’s Perth office as of 24 August 2020.

Bringing more than 30 years’ experience as a lawyer and in related commercial roles, Darren is widely recognised for his expertise in competition law and infrastructure access regulation. He will provide specialist expertise to the firm’s clients operating in the electricity, gas, rail, water, port, transport and mining sectors.

Prior to joining Johnson Winter & Slattery, Darren cofounded the boutique commercial law and litigation firm Grondal Bruining serving as its inaugural Managing Director. He was previously a Partner at Ashurst for more than 10 years.

Darren’s work in competition law covers all forms of restrictive trade practices (eg cartels, M&A, misuse of market power, exclusive dealing, RPM and anti-competitive arrangements) and he has a wealth of experience in access regulation, ranging across both Federal and State based regimes and across rail, port, electricity and gas infrastructure. He also regularly advises on statutory interpretation, administrative law, economic and market regulation, and commercial law.

Managing Partner Peter Slattery said the firm was excited to welcome Darren on board.

“Darren has built a strong reputation in the West Australian market for his specialist expertise and deep industry know-how. We have one of the largest and most widely experienced energy and resources practices in Australia. His expertise will perfectly complement the team and provide a unique insight for our clients in the region.”

Darren has been consistently recognised by independent ranking directories as a leading lawyer in energy law, natural resources law and competition law. In addition, he has lectured at Curtin University Law School in Competition Law and Policy, served on the Curtin Law School Advisory Board, and was Deputy Chair of the Law Council of Australia’s Competition and Consumer Law Committee (Perth).

  • acting for Co-operative Bulk Handling  in seeking and negotiating a long term rail access contract under the Western Australian Rail Access Regimeadvising a commodity producer on competition law issues associated with the international joint marketing of substantial amounts of a major commodity into various Asian jurisdictions
