What began as a routine walk along the Lake Michigan shoreline in Shorewood last summer has evolved into a dispute related to the foundational
Wisconsin public trust doctrine. Based on the ensuing fallout, many observers believe this dispute between two Shorewood residents could lead to the Wisconsin Supreme Court revisiting a 100-year-old decision on the limits of public access rights that are enshrined in the Wisconsin Constitution.

Per- and polyfluoroalkyl substances (PFAS) are a class of thousands of human-made chemicals used across a number of industries. Their durability makes them ideal for various uses like stain protection in textiles, machine lubricants, and fire suppression. That same durability has led to their more common name, forever chemicals, as they do not break down easily in the environment and can persist in the human body for long periods. PFAS have been associated with an increased risk of certain…

Initiatives to Combat PFAS Announced After Environmental Regulation Rollbacks
The second Trump term has already been marked by significant environmental deregulation, including targeting major climate change, energy efficiency, environmental justice, and air pollution policies established over the decades since the first wave of environmental regulatory schemes began in the 1970s.[1] These rollbacks have been compounded by reductions in the EPA workforce and budget, including the agency’s scientific research division.[2] The reduction of per- and polyfluoroalkyl substances (PFAS),…

When I started law school, I wasn’t really sure what exactly I wanted to practice. To be honest, I wasn’t even sure at the time if I liked law. I was unsure of myself, I felt out of place in the law school because my classmates seemed to know exactly what they wanted to do and where they wanted to go.

Wisconsin has over 15,000 lakes, and summer often is filled with swimming, boating, and enjoying the state’s waterways. It is also a time where the importance of understanding riparian rights, property rights associated with Wisconsin’s lakes, rivers, and waterways, is heightened. Disputes between riparian owners (lake and river property owners) have become increasingly common as new construction, crowded shorelines, and changes in watercraft have led to increased contact and increased conflict. The latest iteration of this conflict centers around…
