LDT Final Rule Legal Challenges Likely: Attorneys

Share

Six Hogan Lovells attorneys say litigation challenging the FDA final rule asserting the agency’s authority to regulate laboratory-developed tests remains likely, based on longstanding industry claims that the rulemaking exceeds FDA’s authority. Writing in a comprehensive analysis of the final rule that will become effective 7/5, the attorneys note that throughout the lengthy final rule, FDA “explains its rationale for maintaining that it has such authority and that the final rule does not create new authority to enforce against violative test manufacturers because enforcement discretion is voluntary on the part of the agency and never represented a lack of authority to oversee these products.”

The attorneys say the likelihood of stakeholder success against the agency will be greater if the Supreme Court overturns the longstanding Chevron doctrine of deferring to an agency’s authority to interpret statutory ambiguity in cases currently before the court.
