TALK: On Litigating for Digital Rights

Sunday, Oct. 27 during the 11:00–12:00 time block

Courts have played an essential role in protecting and promoting human rights over the years — we can see this in groundbreaking judgments from equal marriage and abortion to freedom from torture and the right to protest. Judicial precedent can be an effective means of obtaining change for the better in policy, law and practice, and can empower minorities and others under-represented in the political system to vindicate their rights.

As our lives are increasingly playing out in online and digital spaces, we are seeing an erosion of many of our human rights, including our rights to privacy, free speech, and freedom from discrimination. We need the courts as much as ever to protect our rights in these new and evolving contexts. What are the opportunities that lie in strategic litigation in the digital age, and how can court cases shape and safeguard our digital futures?
