Each post in my 1,000 words series addresses — in roughly a thousand words — a key concept, issue, case or debate relevant to Public Law. The intention is that 1,000 words will evolve into a resource that will address a broad range of key issues in Public Law, and that it will help students better to engage with crucial aspects of the subject. Posts in the 1,000 words series are not intended to replace traditional resources, such as textbooks, but rather to complement them, including by providing additional perspectives and highlighting relationships between the often-interconnected issues that must be confronted if Public Law is to be understood. 1,000 words posts do not aim to provide an exhaustive overview; rather, they seek to offer a particular perspective, or to tackle aspects of topics that students commonly find difficult. Links to each 1,000 words post can be found below. If you wish to receive 1,000 words posts (along with other posts) via email, you can subscribe to the blog.
