The Hamptons have become a mecca for pricey properties over the years, serving as a perfect beachy retreat for wealthy New Yorkers who want to enjoy a break from city living—and seek refuge in the area’s many expansive megamansions.

The popular Long Island enclave boasts dozens of lavish homes, but there is one estate in Sagaponack that eclipses every other property in the region: a $425 million manor owned by a billionaire businessman whose dealings have recently seen him—and his expansive property—thrust back into the headlines.

Ira Rennert, 90, the founder of New York-based Renco Group, a family holding company, bought his beachside home in the 1990s.

The lawsuit was filed in 2007 by nuns from The Saint Louis College for Public Health and Social Justice on behalf of a group of children from La Oroya, Peru, against Doe Run Resources Corp., a subsidiary of Renco.

It claims that Doe Run failed to reduce lead emissions in the mine in order to meet regulations set as part of an agreement between Renco and the Peruvian government.

Renco bought the La Oroya smelter and copper mine in 1997 from a Peruvian state-controlled company. Renco agreed to reduce emissions at the plant within 10 years but struggled to do so, even though the company invested in improvements to the plant and surrounding infrastructure.
