If a court deems a product to present an extreme danger, and that item is the legal cause of an injury, any of its manufacturers may become liable. Under RS 9:2800.54, a product may be considered unreasonably dangerous in its construction, design, warning label, or lack of a warning message. In a lawsuit for inadequate warning, defendant manufacturers may defend themselves by stating that, at the time of labeling, there was no generally accepted scientific or technological data that would warrant such a warning.
