Competition and Regulatory Law

Goodman Derrick’s capability covers both contentious and non-contentious competition and regulatory advice.

“In this highly technical area, outcomes have a crucial effect on a company or individual’s prospects and livelihood. Our approach is based on meeting these needs.”

Stephen Hornsby, Partner, Competition and Regulatory

Contentious Competition Law

We often make claims and complaints to key regulators that are designed to achieve our clients’ commercial objectives. We also defend companies subject to regulatory investigations.

Non-contentious Competition Law

We work with our corporate colleagues to advise clients who are merging or being acquired and who are entering major commercial contracts. The objective here is to ensure that where such transactions require approvals wherever that may be, they are allowed to proceed on favourable terms at the lowest cost.


Our regulatory offering includes advising professionals subject to investigations of their conduct before the relevant professional and sporting tribunals and ultimately in the High Court.
