‘The standout individual at Cahill is Greg Battista who leads the environmental team. I have worked with Greg since the mid 1990s. His breadth of knowledge on environmental issues is outstanding- reflecting the decades of experience that he has working in this field. Greg has the rare gift of combining deep technical knowledge with a highly pragmatic approach. He has the ability to take highly complex facts and to distil these into straightforward and practical advice.’

‘Greg Battista has a very easy-going manner and is highly personable- which to the uninitiated may hide a formidable and sharply independent intellect. He also shows a deep understanding of human nature and how people are likely to react to scenarios. Often it is not so much about the law but how you can explain things and build trust. This combination of skillsets makes Greg a truly exceptional lawyer and he is the ultimate problem solver.’

‘Greg Battista has kept his practice at the forefront of developments for example in relation to ESG. Much of what goes now for ESG are issues that he has been working on for many years- under the banner of sustainability. So although ESG is perceived to be new- most of the issues it relates to eg climate change and biodiversity, are those that he has been working on for nearly 40 years or so.’

‘I have worked with Cahill for a number of years and would have no hesitation in recommending them.’

‘I would particularly like to mention Greg Battista. His legal knowledge and responsiveness is a real strength. I always enjoy working with him and would have no hesitation recommending him to clients.’
