The Fourth Circuit Court of Appeals ruled on August 4, 2026, that an employer is not required to give an employee a chance to correct a Family and Medical Leave Act (FMLA) certification before contacting the employee's medical provider. This decision came in the case of Daniel Mook v. G. Hall, impacting how employers handle FMLA requests and the rights of employees in similar situations.
This ruling is significant for employees who rely on the FMLA to take leave for family health issues. The court's decision clarifies the responsibilities of employers when it comes to verifying medical certifications, potentially affecting future cases involving FMLA claims.
Background
Daniel Mook was a former Assistant Commonwealth’s Attorney for the City of Martinsville, Virginia. He initially took FMLA leave in May 2020 to care for his mother. In late 2021, he requested FMLA leave again for the same reason. To obtain approval for this leave, Mook submitted a certification form filled out by himself and signed by a nurse, Scott Schmidt.
However, after submitting this form, Mook's supervisor, G. Andrew Hall, became concerned about the authenticity of the certification. Hall's assistant informed him that Mook had filled out parts of the form that were supposed to be completed by a medical professional. Hall then contacted the nurse's office to verify the signature without giving Mook a chance to correct the certification.
Mook was eventually terminated after Hall accused him of poor judgment and dishonesty regarding the certification process. Following his termination, Mook filed a lawsuit against Hall and the City of Martinsville, claiming they interfered with his FMLA rights by contacting the medical provider without giving him the opportunity to address any issues with the certification.
The Ruling
The Fourth Circuit Court, in a published opinion written by Judge Rushing, ruled that Hall was entitled to qualified immunity because it was not clearly established that an employer must give an employee a chance to cure any inauthenticity before contacting a medical provider. The court stated, "We conclude the answer is no; therefore, we vacate the district court’s contrary judgment denying qualified immunity to the defendant employer on this basis."
The court emphasized that the regulations surrounding the FMLA do not explicitly require such a cure period for authentication issues. The ruling indicated that Hall’s interpretation of the regulations was reasonable, as the terms used in the regulations did not clearly establish Mook’s right to a cure period in this context.
Impact
This ruling has significant implications for both employers and employees. It clarifies that employers may contact health care providers to authenticate FMLA certifications without first allowing employees to correct any potential issues. This decision could lead to more stringent practices by employers when verifying FMLA requests, potentially affecting how employees approach their leave requests.
Furthermore, the ruling raises questions about the application of qualified immunity in FMLA cases. The court did not definitively decide whether qualified immunity is available for FMLA interference claims, leaving that question open for future consideration. This ambiguity may lead to further legal challenges and discussions about employee rights under the FMLA.
What's Next
The district court will need to address whether qualified immunity is a valid defense for FMLA interference claims on remand. This decision will be crucial in determining how similar cases are handled in the future.
