US: Federal District Court Judge John E Steele has issued orders dismissing all claims against National Gypsum in the Brincku and Brucker lawsuits, which had claimed that National Gypsum's US-made wallboard had caused the same corrosive effects in the plaintiffs' homes as allegedly defective Chinese wallboard.
The lawsuits alleged that the company manufactured defective wallboard, which contained high levels of sulphur, released hydrogen sulphide gas from bacteria and corroded copper and other metals inside their homes. Unrebutted scientific evidence provided by the company proved this was not the case.
"We are extremely pleased that our company's products and reputation have been completely vindicated," said CEO Thomas C Nelson. "This ruling confirms what we have said all along: National Gypsum wallboard is a high-quality, safe and environmentally-sound product. Every single false allegation has been rebutted by sound science from the nation's leading laboratories and safety experts."
The court's ruling concludes a long saga which began in 2009. In response to the allegations, the company engaged Packer Engineering and Columbia Analytical Services, two independent testing laboratories, to conduct elemental sulphur, copper corrosion and gas chamber tests on the company's wallboard. Other professionals also tested the air, water and surrounding environments of the homes. These results were consistent with studies done for the Consumer Products Safety Commission by the Department of Energy's Lawrence Berkeley National Laboratory and Environmental Health & Engineering.
The dismissal of the Brincku and Brucker lawsuits is the latest in a series of similar cases that have been thrown out of court. In April 2011 an Arizona putative national class action case against National Gypsum was voluntarily withdrawn after the plaintiffs admitted that there was no scientific or causal evidence to support it. In October 2011, an Alabama lawsuit was dismissed with prejudice, meaning the plaintiffs are barred from bringing the same claim against the company in the future.
