Final answer:
In an LLP, partners' liability is generally limited to their investment in the firm and they are not liable for the negligent acts of other partners unless they were directly involved. Therefore, regarding Ziad's negligence, other partners in the LLP would not likely be held liable for the harm caused to Dania.
Step-by-step explanation:
The question concerns the liability of partners in a limited liability partnership (LLP) when one partner acts negligently during the course of their professional duties. In an LLP, the structure is designed to limit the liability of the partners to their investment in the firm, and they typically are not liable for the negligent acts of their partners committed in the course of the LLP's business. Therefore, if Ziad, a partner in the LLP, negligently harms Dania while performing a root canal, the court would most likely find that the other partners in the LLP are not liable for Ziad's negligent acts unless they were directly involved or supervising the procedure. This would mean that only Ziad could be held liable for the harm caused to Dania unless specific circumstances suggest otherwise, such as a partner's direct involvement or supervision.
