Reddit and an advocacy group led by a New South Wales state MP are challenging Australia's under-16s social media ban in the High Court, according to a Guardian report on the challenge. The Guardian reported that the ban, which it called "world-leading", will face its first major legal challenge on Tuesday.

According to the Guardian, the challengers are Reddit and the Digital Freedom Project, which is headed by John Ruddick, a NSW state MP. The Guardian said they seek to overturn the ban on the grounds of implied freedom of political communication. The report was written by Josh Taylor, the Guardian's technology reporter.

BBC News separately reported that a legal challenge to Australia's social media ban will start in the High Court. In its BBC News report on the legal challenge, the outlet said a rights group will argue that the policy robs under-16s of their right to free communication. The BBC summary does not name that group.

The two accounts describe the legal argument in different terms. The Guardian framed it as implied freedom of political communication, while BBC News described a right to free communication. Neither account states whether the BBC's rights group is the Digital Freedom Project.

The material provided does not describe the outcome of the case or any court timetable beyond the start on Tuesday, as the Guardian reported. The Guardian's summary also refers to a point nearly 11 months earlier, but the text is cut off before it describes that point.
