Professor Laycock's commentary is written in response to Lea Brilmayer's article in this edition. Brilmayer and Laycock agree that states owe equal treatment to citizens of sister states, and that the obligation does not extend to the exercise of government power. But Laycock would derive these rules from constitutional text and structural needs of the federal union. He think that Brilmayer's broader political theory is only marginally relevant to their shared conclusion.
