Kuby defended Raphael Golb, the son of a biblical scholar. Golb had sent emails wherein he impersonated critics of his father's and falsely admitted committing various defamatory acts, including academic fraud; he was arrested in 2009. Charged with multiple felonies and misdemeanors, Golb was convicted at trial and appealed to New York's Supreme Court, which affirmed the charges. Golb then appealed to the New York Court of Appeals, the highest court in New York City. They dismissed some of Golb's convictions, such as identify theft and aggravated harassment (striking down the latter as unconstitutionally vague and overbroad), but they upheld others, including criminal impersonation and forgery.
