Notable cases In
National Trust for Historic Preservation in the United States v. United States Department of Veterans Affairs, et al., Fallon ruled against two preservationists who did not want the U.S. Department of Veteran's Affairs and the State of Louisiana to build two new hospitals near the French Quarter in New Orleans. On March 31, 2010, Fallon found no reason to prevent the building project valued at $2 billion to move forward. Fallon's ruling found that there were enough environmental impact studies completed before moving the project forward, a main objection by the National Trust for Historic Preservation. In
Fernandez v. Knauf, et.al, Fallon presided over a trial for many homeowners who sued Knauf Plasterboard because the drywall has a sulfur type substance that deteriorated the drywall causing concerns that their homes may be unlivable. Fallon heard the case as part of 600 different cases that were consolidated into a special multi-district litigation case that would allow many other home owners to settle their cases out of court. In December 2011, Knauf proposed an unlimited settlement to repair the homes with the defective drywall. In addition, the company offered $30 million for those who reported health problems because of the material. ==Honors==
