Helen Kvelde and Dominique Jacobs, members of activist group the Knitting Nannas, launched a challenge in the NSW Supreme Court through the Environmental Defenders Office in October 2022.
They argued section 214A of the Crimes Act 1900 and clause 48A(1) of the Roads Regulation 2018 were "unconstitutional as they impermissibly burden the implied freedom of political communication of the NSW community".
