[Update Feb 19, 2014:

This thread is no longer being updated all that much. As Bitcoin further permeates the world, most every nation (or state, etc.) will have content specific to that jurisdiction's involvement with Bitcoin.   Feel free to continue posting as you wish, but this thread will no longer be even close to being a comprehensive list as it had been for a period of time.

This list is to serve as an index to all the events in which Bitcoin-related topics interact with the courts, police, regulators, etc.

This is similar to how the NEW Articles in the Press Forum thread serves as an index to media mentions.

Topics related to regulations, taxes, etc. are also cataloged in a Bitcoin.it Wiki article:

I'm hoping for this thread to remain an index, mostly with just a brief summation and then links towards other threads and external sources -- rather than be where discussion for each index entry occurs.   If an entry is made, feel free to reply with a link to a relevant thread where further discussion occurs or to other related content.
