Ninth Circuit Preemption Case Raises Questions about the Authority of State and Local Governments to Regulate Energy Efficiency through Building Codes

On June 25, 2012 -- while Constitutional Law wonks waited with bated breath for the Supreme Court’s decision on the Patient Protection and Affordable Care Act, which came just three days later -- the U.S. Court of Appeals for the Ninth Circuit rendered an interesting opinion on the relationship between the U.S. government and the States, which basically went unnoticed.

Maryland Legislature Poised to Extend Option of "Benefit" Status to LLCs

Maryland limited liability companies that pride themselves on their commitment to environmental and social responsibility soon may be able to obtain legal recognition, separate from their less magnanimous competitors.  If passed, Senate Bill 595 and its companion House Bill 1151 will allow willing limited liability companies to elect “Benefit” status--similar to the “Benefit” status already available to Maryland corporations. 

Green Is in the Eye of the Beholder

Next November, a federal court in California is scheduled to preside over an important “greenwashing” class action lawsuit.  In Koh v. S.C. Johnson & Son, Inc., No. C-09-00927 RMW, a plaintiff, on behalf of himself and other individuals that purchased various S.C. Johnson & Son household cleaning products, sued that company, alleging that the company’s “Greenlist(tm)” labeling system was false and misleading. 

Trinity Assembly of God v. People's Counsel for Baltimore County

In 1802, Thomas Jefferson wrote in a letter to the Danbury Baptists that the American people have "declared that their legislature should 'make no law respecting an establishment of religion, or prohibiting the free exercise thereof,' thus building a wall of separation between church and State." It is doubtful that Jefferson had in mind the Religious Land Use and Institutionalized Persons Act of 2000, 42 U.S.C.A.
