Supreme Court voids proceedings due to res judicata and identical parties in reversed roles.

The Supreme Court voided the proceedings because the case involved identical parties and legal grounds as a previously concluded final judgment. The plaintiff, now acting as the appellant, sought recovery of funds already paid to retirees based on a prior court order. The court ruled that initiating a new lawsuit on the same subject matter between the same parties, even with reversed procedural roles, violated the principle of res judicata.
