A Plaintiff and an Intervenor-Plaintiff decide to make a joint offer of judgment to a group of 4 Defendants of which totals $100,000 (apportioned as $25,000 to each of the 4 Defendants). All 4 Defendants reject their offer of judgment and the case proceeds to a trial. At trial, the jury awards the Plaintiff $100,000 and the Intervenor $200,000 for a total of $300,000. Would the Rule 68 sanctions apply to the 4 Defendants in such a scenario? Are all 4 Defendants responsible for the costs sanctions for both Plaintiff and Intervenor?
