A lot happened in the legal industry in 2012. Companies and law firms alike struggled in the face of the still-difficult economy, and not all of them came out on top. Political turmoil reached a tipping point, new regulations came into effect, cases were won, lost and settled, criminals were jailed.

But through all the ups and downs, these 20 stories stayed with us. They’re the ones we feel will have lasting impact, the historic decisions, the game-changing regulations and shocking scandals. As 2012 winds to a close, we hope that reviewing these stories will help in-house counsel prepare for the new challenges 2013 will bring.
