Not long after the passage of an E.U. law limiting bonuses for bankers in the E.U., one state government (the usual suspect) filed a lawsuit in federal court (the ECJ) to contest the new law before it even went into effect. Perhaps it could have been said that 'banker-bonus caps is to Britain as "Obamacare" is to Texas.' Although federal overreach was an element in both complaints, we can still ask what was the true basis of Britain's suit.
