To examine the practical case for Indigenous jurisdiction. Does it work? This is a pressing issue. If you are an advocate for Indigenous jurisdiction, in today’s political environment you need all the arguments you can muster. If you are a skeptic on the subject, or even an opponent, it seems to me the public good still requires you to consider all dimensions of the case, including the practical one. For after all, if one of the purposes of public policy is to improve public welfare, including Indigenous welfare, then the question of efficacy deserves close consideration, regardless of how the other arguments fare.
