5th Cir.

Nestor Beltran v. Lockheed Martin Corporation

March 20, 2026 ·25-10808 ·Per Curiam · By Aisha Johnson

The Fifth Circuit affirmed summary judgment for Lockheed Martin, ruling that an employee's communications regarding policy disagreements did not constitute protected whistleblowing under the NDAA. Even assuming the activity was protected, the court held the employer proved by clear and convincing evidence that the termination was based on repeated insubordination.

Nestor Beltran, a quality inspector for Lockheed Martin, was suspended twice for insubordination in late 2022 and early 2023. Following his first suspension, Beltran sent an email to his department director raising concerns about internal policy changes, specifically regarding 'Avoid Verbal Orders' (AVOs), and alleging that supervisors undermined quality inspectors. He also expressed personal grievances about being passed over for advancement. After a second suspension for refusing to follow direct orders, Lockheed convened a Disciplinary Review Committee which unanimously recommended termination. Beltran sued, alleging retaliation and discrimination under Title VII and retaliation under the National Defense Authorization Act (NDAA). The district court granted summary judgment for Lockheed on all claims. Beltran appealed only the dismissal of his NDAA retaliation claim.

The Fifth Circuit reviewed the grant of summary judgment de novo. The court first outlined the NDAA's whistleblower provision, which protects employees who reasonably believe their disclosure evidences gross mismanagement, waste of funds, abuse of authority, danger to public health, or violation of law related to a federal contract. To prevail, an employee must show a protected disclosure, an adverse action, and that the disclosure was a contributing factor. If established, the burden shifts to the employer to prove by clear and convincing evidence that it would have taken the same action anyway. The court applied the three-factor test from Carr v. Social Security Administration to evaluate Lockheed's affirmative defense. First, the evidence of insubordination was significant; Beltran refused direct orders twice in four months, and other employees in his role completed the tasks without issue. He also had a lengthy disciplinary record involving harassment and policy violations. Second, there was no evidence of retaliatory motive. The manager who investigated Beltran knew of the email but testified it did not cause concern beyond standard ethics protocols, and Beltran conceded he had no evidence the manager was upset. Third, Lockheed demonstrated it disciplined non-whistleblowing employees similarly for insubordination. The court concluded Lockheed met the high burden of clear and convincing evidence, establishing an abiding conviction that Beltran would have been fired regardless of his email.

This decision reinforces the high bar for NDAA whistleblower claims, emphasizing that general policy complaints and personal grievances do not trigger statutory protection. It clarifies that employers can successfully defend against retaliation claims by demonstrating strong, non-retaliatory reasons for termination, such as repeated insubordination, provided they meet the clear and convincing evidence standard. The ruling affirms the district court's dismissal, leaving Beltran without a remedy for his alleged retaliation.
