Under what conditions must an attorney withdraw from a pending case?

An attorney must withdraw from a pending case under specific circumstances that are guided by ethical rules and professional conduct standards. The most significant condition is when continuing representation would violate a law or ethical rule. For instance, if the attorney learns that the client is involved in illegal activity, or if the attorney encounters a conflict of interest that cannot be resolved, withdrawal is mandated to uphold the integrity of the legal profession.

Additionally, if the attorney has been fired by the client, they must also withdraw from the case. This ensures that the client’s rights are protected and that the attorney does not continue to work on a matter against the client's wishes.

Thus, the requirement for withdrawal under condition C encompasses both the obligation to respect the client's decisions and the necessity to comply with legal and ethical standards, making it the correct choice in situations where an attorney's continued involvement may be inappropriate or impermissible.
