.nz justly prides itself on a robust, cheap and fair disputes resolution service. It's based in New Zealand, a country which is regularly ranked in the top three least corrupt in the world, and currently number 1.
InternetNZ is an open membership charitable society that is the delegated country manager for .nz and has the objective to strive for an open and uncapturable internet.
They delegated the day to day management of .nz to www.dnc.org.nz, who also run the disputes service (http://dnc.org.nz/story/drs-home), while the register itself is delegated by InternetNZ to www.nzrs.net.nz. This structure was set up to ensure that these sorts of issues would be resolved appropriately.
I note that the new gTLDs (.whatever) will need to use ICANN's standard dispute resolution process, which is convoluted, lengthy and expensive. I do not know how these will fare under SOPA et al.
