First they came for the email account content, then the Facebook content, and now lawyers are after Twitter content. The question becomes "Who owns the Tweets?" Although this case doesn't involve family law issues, the prospect remains that the decision could impact family law cases.
Twitter says that its users own their tweets, and all that personal information. The court says Twitter does, and should hand them over when subpoenaed. This week Twitter has filed an appeal to New York Supreme Court, the second time it's filed a motion in this case.
Bottom line: Twitter says that it makes it clear in its terms of services that users own their content and they have "a right to fight invalid government requests," i.e. subpoenas.
