Lawsuit 1: Privacy
Let's say your team of lawyers put together a solid BYOD user policy, one that pretty much doesn't give an employee much expectation of privacy. You're covered, right? Don't be too sure. Managers need to be well-trained on the BYOD user policy, too.
In the case of City of Ontario vs. Quon, police sergeant Jeff Quon and others sued the city alleging violation of their constitutional rights because personal messages on a department-issued pager were audited and led to Quon's firing. While the Supreme Court ultimately sided with the auditors, one of Quon's superiors verbally assured him that messages would not be monitored, thus igniting a controversy over the expectation of privacy.
