20 Cal. 3d 413 (1978)

Study notes for Barker v. Lull: professor notes, cold call prep, exam angles, and memory aids.

A product is defectively designed under strict liability if it poses an unreasonable risk of harm, failing to meet consumer safety expectations.
Professor Notes

Barker v. Lull is a pivotal case concerning product liability and the standard of strict liability as it relates to defective design. The California Supreme Court's decision emphasized that manufacturers have a heightened responsibility to ensure their products are safe for consumer use. Professors may highlight how this case redefined the expectations for safety that consumers hold, underscoring that a product's design must not only be functional but also capable of meeting consumer safety expectations. Additionally, professors often discuss the implications of this case for manufacturers and designers in the construction industry, where the stakes of equipment safety are markedly high.

In teaching this case, it is also important to note the court's rejection of a more narrow view of consumer expectations regarding product safety. By ruling in favor of Barker, the court shifted the focus to a broader interpretation of reasonable safety standards that manufacturers must adhere to. This decision is frequently cited in discussions of strict liability and serves as a cornerstone in understanding the complexities of product safety and consumer rights in tort law.
