A California appellate court has ruled that Amazon can be held liable for injuries caused by defective products sold by third-party sellers on its platform. The court found that Amazon's role in storing, packaging, and shipping the product made it a pivotal part of the chain of distribution, and therefore liable under California law. This ruling may have significant implications for Amazon's business model and could potentially lead to changes in how the company handles third-party sales. The case is expected to be appealed to a higher court.
