Brian J. Paul is an appellate lawyer and leads law teams in high-stakes commercial litigation. He has briefed and argued everything from weighty abstract constitutional issues to dollars-and-cents business issues and everything in-between, both on appeal and in trial courts around the country. A member of the American Law Institute, recent past-president of the Seventh Circuit Bar Association and top-tier ranked Chambers appellate lawyer, Brian had one client say about him: “Brian is one of the most respected and skilled appellate lawyers, not only in Indianapolis but across the country. He is trusted to deliver timely guidance on complex issues.” Another said: “He is excellent. I enjoyed working with him. He is able to put things into layman’s terms and explains things really well. His written and oral advocacy are short, crisp and to the point.”
Clients hire Brian to digest the complex, and make the complex simple and compelling for busy, generalist judges. In his writing, he strives to cut through jargon and legalese, and distill things down to what’s important. In his oral advocacy, by intense preparation, he strives to be the advocate whom judges trust for the right answers. In the dozens of cases he has argued, Brian has helped clients win on both sides of the “v.” His recent representations include:

ROGER MARTELLA co-leads the Environmental practice group at Sidley Austin LLP. He rejoined Sidley Austin LLP after serving as the General Counsel of the United States Environmental Protection Agency, concluding 10 years of litigating and handling complex environmental and natural resource matters at the Department of Justice and EPA. In 2015, Roger was recognized by Who’s Who Legal as the environmental lawyer of the year globally.
Roger’s practice focuses on three primary areas. First, Roger advises companies on developing strategic approaches to achieve their goals in light of rapidly developing demands to addressclimate change, promote sustainability and utilize clean energy. Second, Roger handles a broad range of environmental and natural resource litigation and mediation. Third, Roger advises multinational companies on compliance with environmental laws in the United States, China, the European Union and other nations.
Roger counsels approximately 50 of the world’s leading conventional and renewable energy, industrial, transportation, agricultural, forestry, and technology companies on bet-the-company environmental issues, regulatory matters, and litigation including transitioning to an era of legal controls addressing greenhouse gas emissions, increasingly stringent pollutant controls, alternative and clean energy, hydraulic fracturing, and sustainability both in the United States and abroad.
Roger employs a strategic, forward-looking approach to solving emerging law and policy issues across the world that have the potential to create both opportunities and risks for domestic and multinational energy and manufacturing companies and industries. Roger’s approach is to build a collaborative and coalition-building framework that seeks the strongest possible results through up front coordination with government, industry, and NGO stakeholders, leveraging strong honest broker relations with government officials and understanding of government approach to realize resolutions that have led to extraordinary favorable resolutions offering significant regulatory relief to industries and pennies-on-the-dollar enforcement settlements for companies.
Roger was unanimously confirmed by the United States Senate as EPA General Counsel. In that role, Roger served as EPA’s chief legal advisor supervising an office of 350 lawyers and staff in Washington and 10 regional offices. In particular, Roger led the team responsible for developing for the first time under the Clean Air Act the federal government’s climate change legal framework and options in response to the landmark Supreme Court decision Massachusetts v. EPA, which held greenhouse gases to be air pollutants under the Clean Air Act.
