I want to know the answer to the following question:
Who was at the forefront of the fight to change the laws on defective products?
All the background I'm provided with is that "In 1963, Roger J. Traynor of the Supreme Court of California threw away legal fictions based on warranties and imposed strict liability for defective products as a matter of public policy in the landmark case of Greenman v. Yuba Power Products.". Is that enough to answer the question?
