Al Regnery has addressed the lawsuit of five conservative authors, as detailed in the New York Times:

The merits of the lawsuit are hardly worth discussing. To anyone in the book publishing industry they're laughable. I'm a lawyer and know that the contracts they signed are clear and transparent, and are similar to the contracts used throughout the industry. I also know that Regnery puts marketing muscle and expertise behind its books like nobody else in the business -- something that each of the five authors involved benefited from enormously. These disgruntled authors are, perversely, complaining about that muscle. But it's one of the reasons why Regnery has the success it does in putting conservative books where the New York Times doesn't want them -- on its bestseller list.
