Opinio Juris (blog)
Opinio Juris is a blog dedicated to the informed discussion of international law by and among academics, practitioners and legal experts, published independently in cooperation with the International Commission of Jurists. The blog has been described as "the leading blog on international law" in Lawfare (blog). It is one of the two most widely read international law blogs, together with EJIL: Talk!. Background 
The blog was started in 2005 by Chris Borgen (St. John’s University); Peggy McGuinness (St. John’s University); and Julian Ku (Hofstra). Kevin Jon Heller (University of Copenhagen) joined in 2006. In 2007, State Department Legal Adviser John Bellinger became a guest blogger for a week. This marked the first time that a US government official blogged in an official capacity on international law. Notable contributors to the blog have included British-French lawyer, academic, and author Philippe Sands, American lawyer and U.S. official Harold Hongju Koh, and Diego García-Sayán, UN Special Rapporteur on the independence of judges and lawyers.
