Adams v. Little Giant Ladder Systems, LLC, 3:22-cv-00460

Jason Adams was injured when a rung on his Little Giant ladder detached during ordinary use; he claims no misuse occurred.
The lawsuit asserts products liability claims (including strict liability, negligence, and breach of warranty) against Little Giant Ladder Systems, LLC.
Both parties filed motions for summary judgment and moved to exclude each other's expert testimony.
The court excluded plaintiffs’ expert (Kassekert) as unqualified on weld/material defect issues, but allowed defendant’s expert (Wright), a metallurgical engineer, to testify.
Plaintiffs did not oppose dismissal of their failure to warn and punitive damages claims.
The court was asked to decide if the remaining claims could proceed based on circumstantial evidence and warranty terms.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Exclusion of Experts	Defense expert should be excluded; without her, summary should be granted for plaintiff.	No basis to exclude; their expert’s testimony is admissible.	Defense expert is allowed; plaintiffs’ motion for summary judgment denied.
Product Defect (Strict Liability)	Circumstantial evidence allows claim to proceed (malfunction theory).	No qualified direct expert evidence to show defect.	Sufficient circumstantial evidence exists; claim proceeds under malfunction theory.
Design Defect (Plastic Cap & Weld)	Faulty design: plastic cap concealed a critical weld flaw.	No admissible expert evidence (post-exclusion); safety standard justified cap.	No qualified evidence supports claim; summary judgment for defendant on this aspect.
Breach of Warranty	Warranty covers ladder failure under normal use, can be proven circumstantially.	No defect proven; limited damages per warranty; ladder not returned for inspection.	Court requests further briefing on damages/return requirements; decision abeyed.
