Without free speech one cannot claim other liberties, or defend them when they are attacked. Without free speech one cannot have a democratic process, which requires the statement and testing of policy proposals and party platforms. Without free speech one cannot have a due process at law, in which one can defend oneself, accuse, collect and examine evidence, make a case or refute one. Without free speech there cannot be genuine education and research, enquiry, debate, exchange of information, challenges to falsehood, questioning of governments, proposal and examination of opinion. Without free speech there cannot be a free press, which...is necessary...as one of the two essential estates of a free society (the other being an independent judiciary).
