Common design

Common design could, in principle, be invoked against a defendant in a claim based on misuse of confidential information, however, in order to be party to a common design, a defendant had to share with the other party each of the features of the design which made it wrongful

If, and only if, all such features were shared, the fact that some parties to the common design did only some of the relevant acts, while others did only some other relevant acts, would not stop them all from being jointly liable.
