Over the last few decades, prior approval requirements were considered an extraordinary remedy in merger settlements, yet their use has fluctuated in agency enforcement across recent administrations. Where do the FTC and DOJ stand in their current practice? Bilal Sayyed, a Counsel at the Cadwalader law firm, and antitrust professor and former FTC policy leader, speaks with Anora Wang and Jeny Maier about the role of prior approval provisions in modern merger enforcement and what their recent rise—and retreat—signals about agency policy. Listen to this episode to learn how prior approval differs from traditional HSR review, when agencies have relied on such provisions, and what the evolving approach means for merging parties and future dealmaking.

In 2006, various parties came together to form Brazil's Amazon Soy Moratorium in an effort to curb illegal deforestation in the Amazon Rainforest. Today, challenges regarding Brazil's Soy Moratorium continue to mount, with passionate advocacy from farmers, environmentalists, government agencies, and international organizations. What might seem a cut-and-dry conflict between free enterprise and environmental conservation becomes more complicated when we delve deeper. With an antitrust cartel investigation in limbo, a pseudo-private agreement to arguably higher deforestation standards than those instituted by the government, and international observers on the scene, including customers and climate activists, the facts surrounding Brazil's Soy Moratorium are ripe for unpacking. Our guest today is antitrust attorney Eduardo Frade, who joins Barry Nigro and Anora Wang to discuss Brazil's Soy Moratorium and the various antitrust and competition questions it raises.
