Those among us who’ve had hefty legal bills have wondered why they were so high. There’s lots of lingo for that: “Bill padding.” “Churning.” Even “feather bedding.”

With the acknowledgement that the vast proportion of lawyers only demand what they’re rightly owed, emails uncovered in a court filing last week suggest some have indeed been gilding the lily.

As one of the attorneys wrote to a colleague, “Churn that bill, baby!”

“You have some incredibly damning statements in these emails, basically acknowledgements from these lawyers at this firm that there were some shenanigans going on in the way they worked,” said Peter Lattman, who wrote about the suit for The New York Times Dealbook.

One of the temptations facing lawyers is the billable hour, a standard practice in the legal industry. That is, instead of a flat fee for services, firms charge for the amount of time worked on a case. That provides an incentive to put an excess of lawyers on a wealthy client’s case (“feather bedding”) or to do unnecessary or irrelevant research (“churn”). Although considered unethical, Lattman’s sources estimate that the practices are common.

The firm at the center of the lawsuit, DLA Piper, went a step further in openly acknowledging their efforts to churn legal bills. With 4,200 attorneys, it’s the world’s largest law firm. In other words, plenty of people to add to a case if needed.

And an extra hour here or there may not sound like much, but prestigious corporate firms can charge in excess of $1000 per hour, according to Lattman.
