Dennis Loether, Bartier Perry

Dennis leads our Environment and Planning team and has experience advising statutory authorities, local governments and private sector clients. His expertise cuts across all areas of planning and property law, as well as environmental issues.

Over fifteen years of practice in environmental and planning law have given Dennis a detailed technical knowledge. Because he has acted for both public and private sector clients, Dennis has the ability to understand competing arguments and see both sides of an issue, which informs his strategic advice.

What Dennis’s clients say

“Dennis put together a group of consultants, solicitors, junior and senior barristers who helped cement a solid case in a complex development application that ended up in the Land and Environment Court against two large corporate companies and the local council. He guided his team through a David & Goliath battle in which many people thought not possible to win but win we did, thanks to Dennis with his professional approach and hard work we got the result we were looking for.”- Joe Barca, Director, Barca Metals
