Roma and Swain are the two partners in Roma & Swain Attorneys, LLP, a limited liability partnership. Roma supervises their firm's associate attorney Taylor, who negligently fails to appear in court on behalf of Umberto, a client. Liability to Umberto rests only with

Roma and Taylor.

Explanation:

Every person is liable for negligence performed by them. Taylor failed to appear in the court so Taylor is liable. Roma on the other hand was supervising Taylor which makes her liable as well for his negligent supervision of Taylor.

Other partner will not be liable as it is limited liability partnership.
