Client hires attorney.  Attorney works on case, very hard, and does a good job?  Other problems arise, such as criminal investigations of client.  Client drops case.  Attorney loses contingent fee.  Can attorney sue client for lost fee?  Here, the case says NO !.

"In a short opinion, the Court rejects the plaintiff law firm’s effort to create a new rule of client liability. The Court explains that the law firm’s legal theory would distort the complex calculus about whether to pursue litigation and “mock[] the idea of client control.” In the instant case, it’s no surprise that the client decided not to pursue civil litigation in the face of multiple criminal investigations and fraud claims, and the client acted within its rights by opting to concentrate its resources and energy on these more serious legal issues. Although the result is “admittedly harsh” to those lawyers who toil away with the expectation of a windfall contingency, that’s just the nature of the game. "
