Chen v. Rubio

Standard of Review

The Second Circuit reviews the district court's grant of summary judgment de novo. De novo review means the appellate court considers the case anew, without deference to the trial court's legal conclusions. This standard applies because the district court's decision rested on an interpretation of law, specifically the application of the "actual malice" standard.

Procedural Posture

Plaintiff Chen sued Defendant Rubio for defamation. The district court granted summary judgment in favor of Rubio, finding that Chen failed to present sufficient evidence to establish actual malice. Chen appealed this decision to the Second Circuit.

Burden of Proof

The plaintiff, Chen, bears the burden of proof to establish actual malice by clear and convincing evidence. This standard is higher than a preponderance of the evidence and requires the plaintiff to show that the defendant published the defamatory statement with knowledge that it was false or with reckless disregard for whether it was false.
