Sumner and Shari Redstone’s National Amusements Inc. sure likes to keep bankers and lawyers employed.

When Sumner, the controlling shareholder of the $40 billion CBS and Viacom empire, wanted to oust CEO Philippe Dauman, the courtroom was packed with 43 lawyers representing corporate executives and Redstone family members. The sea of blue suits stunned the case judge.

Litigation went on for months, with cases fought in Massachusetts, Los Angeles and Delaware, until Dauman agreed to step down in August with a $72 million payoff. He was replaced by Chief Operating Officer Tom Dooley, who exited with a $63 million payout in September.

Early that month, NAI hired Barclays and Evercore Partners to help figure out how to manage its 80 percent voting stake in the two media entities.

Then, by Sept. 28, NAI called for a merger of CBS and Viacom, a plan since abandoned but which will result in a huge bill for shareholders.

CBS hired Moelis and Goldman Sachs to represent its interests in a merger, while an independent special committee of CBS board directors hired Lazard and law firm White & Case.

On the Viacom side, its special committee hired Morgan Stanley, Allen & Co. and LionTree Advisors, along with law firm Debevoise and Plimpton.

And let’s not forget the law firms hired to litigate claims against Sumner Redstone by gal pal Manuela Herzer. Or his more recent legal efforts to get Herzer to return gifts.
