The issue of whether human rights treaties apply in the US without any implementing legislation is largely a red herring. There are numerous Human Rights laws in the US, at both the Federal and state level.

In the US, Federal Human Rights Laws include, without limitation:

In addition, many portions of the US Constitution and particularly the "Bill of Rights" (i.e., the first 10 amendments) protect human rights.

Here's a page with discussion and links relating to both California law and Federal law protecting human rights: https://oag.ca.gov/civil/lawleg#federalLaws

Also this: https://oag.ca.gov/civil

California passed a landmark human rights law in 2015 that extended the ability to make claims for human rights abuses, among other things: https://www.justsecurity.org/26619/california-human-rights-legislation/

Here's a Wikipedia entry on another California human rights law, the Unruh Act: https://en.wikipedia.org/wiki/Unruh_Civil_Rights_Act

If you have 90 minutes, you can watch this webinar from the California Department of Human Resources: "Overview of Civil Rights Laws in the Workplace": https://www.youtube.com/watch?v=JNK1bIHE3HY

Here's an interesting scholarly paper on using international human rights instruments in state courts: https://opportunityagenda.org/files/Human_Rights_in_State_Court.pdf (copy attached) Red herring or not, this discusses how treaties have actually been invoked effectively in state court litigation.

Here's a blog called "Human Rights at Home," which covers US human rights laws and issues (as well as some international human rights issues): http://lawprofessors.typepad.com/human_rights/

Here's a white paper from the Human Rights Institute at Columbia Law School (my alma mater) on using human rights treaties at the state and local level. It also has a good, if slightly self-flagellating, summary discussion of human rights in the US, at the beginning of the document: https://web.law.columbia.edu/sites/default/files/microsites/human-rights-institute/files/Bringing%20Human%20Rights%20Home.pdf (and attached).

As an aside, I would also note that California is one of the leading states (if not the leading US state) with regard to state legislation protecting human rights. So, if you wanted to choose an applicable state law in the US from which to derive human rights protections, you could scarcely do better than California. Among other things, California has a law specifically protecting the human right to water; here's an implementation framework for that law: http://www.ushrnetwork.org/resources-media/human-right-water-bill-california

I could go on, but I think it's sufficient to demonstrate that state and federal laws applicable to ICANN include many laws protecting human rights.

The one thing I haven't found in the bit of searching I have done, is a comprehensive resource ("one stop shopping," if you will) for federal and state human rights laws, whether generally or applicable to California (although the second link above comes close on the latter front). If there are any eager law students look for a note topic, or professors looking for an article topic, that might be an interesting one (if I am in fact right that no such resource yet exists; I have hardly plumbed the depths....)

Best regards,
