We are very sorry to mark the passing of Professor Michael W. Lewis of Ohio Northern University. Mike spoke and wrote with rare authority as someone who was not only a leading international law and national security scholar who engaged in broader public discourse (see his many debates, presentations, and interviews), but also as a former Naval aviator and TOPGUN graduate,...

In March 2012 An Hertogen and Jessica Dorsey joined Opinio Juris as our first two Assistant Editors. Over the years, both have contributed immensely to Opinio Juris. Today, we bid An farewell as she enters a new phase in her career. You may be most familiar with An’s work writing our Weekly Round-Ups and well as the Events and Announcements posts....

It may be hard to believe, but this week Opinio Juris is celebrating its tenth anniversary. In a placeholder post prior to our commencing regular blogging, Peggy, Julian, and I had explained: Our modest goal is to share with our readers a variety of perspectives on the role of international law in the U.S. and around the globe and to stimulate...

Since Kosovo’s declaration of independence there has been talk about whether there is a “Kosovo precedent,” and, if so, just what does it mean. The International Court of Justice’s advisory opinion captured the imaginations of national parties throughout Europe. For example, Aitor Estaban, a representative from Spain’s Basque Nationalist Party (PNV) said that “the main consequence is that Spain cannot keep saying that the international rules don’t allow for a split of the country for a new Basque independent country into the European Union. So I think that should be already over and that’s good news for us.” (See H. Jamar & M. K. Vigness, ‘Applying Kosovo: Looking to Russia, China, Spain, and Beyond After the International Court of Justice Opinion on Unilateral Declarations of Independence’, 11 German Law Journal (2010) 8, 913, 925.) Will we now add a "Scotland precedent"  as well as  a “Kosovo precedent?"  Today’s referendum in Scotland has been described as a bellwether or a "canary in the coalmine" signaling the future of nationalism within the European Union. There are currently twenty to twenty-five “significant” separatist movements across Europe. (See, Bruno Coppieters, ‘Secessionist Conflicts in Europe’, in D. H. Doyle (ed.), Secession as an International Phenomenon: From America’s Civil War to Contemporary Separatist Movements (2010), 237, 247.) Many writers seem to assume that as Scotland goes so does Catalonia, the Basque Countries, Padania, and any number of other parts of EU countries with their own national aspirations. But is this accurate? Would a “Yes” vote—or even just the fact that there is a vote—form some sort of “Scotland precedent?” First, what do we mean by “precedent?” At times, commentators  use the word to mean, interchangeably, the strict legal sense of a legally binding decision and the looser political sense of a persuasive analogy that can be drawn from a similar case. What role may Scotland’s referendum have in regards to the nationalist movements elsewhere in the EU? Let us consider the number of legal and political factors at play in just one example: Catalonia. At first blush, the situation in Catalonia may seem similar to that in Scotland. As a political entity, Catalonia has some similarities to Scotland (if slightly larger). As Bloomberg News explains:
Catalonia is a region in the northeast corner of the Iberian peninsula with about 7.5 million people compared with the 5.3 million who live in Scotland. Its 193 billion-euro economy is about the size of Finland’s and compares with the 150 billion-pound gross domestic product of Scotland.
Like Scotland, Catalonia has a distinct linguistic and national heritage. It has a special status within the Spanish state with greater autonomy and it has a population that has been seeking greater levels of independence, if not full separation and sovereignty. And the regional government of Catalonia has scheduled a referendum on independence for this coming November. For more on the history of Catalonia, see this. Despite these similarities, most international lawyers could see quickly that a domestic referendum in the UK does not provide binding legal precedent for whether or not a domestic referendum in Spain would actually grant independence to Catalonia. Rather, the issue is one of political precedent: persuasive strength. In an argument supporting Catalonia’s referendum, Carles Boix and J.C. Major wrote in Foreign Affairs that, in their view:
International opinion tends to support this referendum, just as it has supported the one that will be held in Scotland this September or those that took place in Quebec a few years ago. Indeed, finding out where everyone stands would appear to be a necessary step to make an informed decision on how to proceed. And yet the Spanish government has not granted the Catalan authorities the power to conduct what would be a non-binding referendum -- something that would be perfectly legal according to articles 92 and 150.2 of the Spanish constitution.
But even if one is to argue that Scotland’s referendum is persuasive authority, one first needs to consider whether the analogy is a good one. And, for that, we need to consider once again the legal and political situation.

There are many dads who have played make-believe with their little girls, perhaps taking the part of kindly king to his daughter's princess.  Not many people have turned this game into an international legal incident concerning state formation.  But  at least one man has. According to the Washington Post:
Jeremiah Heaton was playing with his daughter in their Abingdon, Va., home last winter when she asked whether she could be a real princess. Heaton, a father of three who works in the mining industry, didn’t want to make any false promises to Emily, then 6, who was “big on being a princess.” But he still said yes. “As a parent you sometimes go down paths you never thought you would,” Heaton said. Within months, Heaton was journeying through the desolate southern stretches of Egypt and into an unclaimed 800-square-mile patch of arid desert. There, on June 16 — Emily’s seventh birthday — he planted a blue flag with four stars and a crown on a rocky hill. The area, a sandy expanse sitting along the Sudanese border, morphed from what locals call Bir Tawil into what Heaton and his family call the “Kingdom of North Sudan.” There, Heaton is the self-described king and Emily is his princess.
Wow. Heaton just upped the ante for all non-royal dads. The Washington Post also reports:
Heaton says his claim over Bir Tawil is legitimate. He argues that planting the flag — which his children designed — is exactly how several other countries, including what became the United States, were historically claimed. The key difference, Heaton said, is that those historical cases of imperialism were acts of war while his was an act of love. “I founded the nation in love for my daughter,” Heaton said.
That’s sweet. Really. But let’s turn to the international legal argument…
