Our December issue features what we believe to be the Top 20 legal news stories of the year—the stories that held our attention, and the legal industry’s, throughout 2012. We painstakingly pared down our list from all the stories we’ve written about this year, but we were interested to see if our readers would have chosen differently.

So we put it to a vote, and these are InsideCounsel readers’ picks for the year’s most important stories.The results are in order from the stories that received the most votes to those that received the least. An asterisk indicates the entries that our readers chose, but which didn’t make it onto our list.
