Legal professionals should approach res sub judice with careful attention to ensure a smooth legal process. First, they must verify whether the issue at hand is already being litigated in another court. If so, they must avoid initiating any parallel proceedings, as this could violate the res sub judice rule. Next, they should focus on the progress of the ongoing case by staying updated on court dates and the status of filings. Legal professionals should also ensure that all arguments and evidence are properly presented in the current forum, avoiding the temptation to raise the same issue elsewhere. Additionally, if a party wishes to appeal or seek further remedies, they must do so through the appropriate channels within the same court or judicial body. Best practices include diligent case monitoring, timely filing of motions, proper documentation, and clear communication with clients regarding the implications of res sub judice on their case. By following these steps, legal professionals can help navigate ongoing cases without complications and ensure efficient case management.
