Court cases

Social media comments and images have been used in court cases including employment law, child custody/child support, and disability claims. After an Apple employee criticized his employer on Facebook, he was fired. When the former employee sued Apple for unfair dismissal, the court, after examining the employee's Facebook posts, reported in favor of Apple, stating that the posts breached Apple's policies. After a couple broke up, the man posted song lyrics "that talked about fantasies of killing the rapper's ex-wife" and made threats. A court reported him guilty. In a disability claims case, a woman who fell at work claimed that she was permanently injured; the employer used her social media posts to counter her claims.

Courts do not always admit social media evidence, in part, because screenshots can be faked or tampered with. Judges may consider emojis into account to assess statements made on social media; in one Michigan case where a person alleged that another person had defamed them in an online comment, the judge disagreed, noting that an emoji after the comment that indicated that it was a joke. In a 2014 case in Ontario against a police officer regarding alleged assault of a protester during the G20 summit, the court rejected the Crown's application to use a digital photo of the protest that was anonymously posted online, because it included no metadata verifying its provenance.
