You work for a major law firm representing a famous entertainer, Jane Lou. Her former boyfriend who has taken nude photos of her wants to publish them in a tabloid. Lou has retained your firm to represent her in a case to prevent the tabloid from publishing the photos. She brings copies of the photos to the firm. Your attorney gives them to you and asks you to file them. As you glance through the photos prior to filing them away, you are called out of your office on an urgent matter. In your hurry, you leave the photos in an envelope on your desk intending to file them away later. When you come back to your office, the photos are gone. They appear in another tabloid the next day. Lou is now suing your firm, your attorney, and you for malpractice.

Let's focus solely on the defenses of the paralegal and attorney - can you think of anything they may claim which would make the firm responsible (and not them individually)?
