Konrad Graf delivers a talk addressing Action-Based Jurisprudence at the Australian Mises Seminar in 2012. The full text transcript with slides can be absorbed here. The talk has six sub-headings:

• The problem of rights violating rights protectors [1:22]
• Differentiating law and ethics [10:47]
• Three core legal theory modules [18:35]
• The full range of responses to aggression [33:56]
• Consistently rights-protecting legal institutions [39:12]
• Who wins and loses from misplaced complexity? [46:36]

There are several questions at the end of the presentation. As usual the above was brilliant. A listing of more timestamps are available in the video description. This is the most cutting edge article on Austro-Libertarianism that exists today.
