Supreme Court dismisses appeal because lawyer representing union lacks individual client power of attorney, requiring court summons to union counsel only.

The Supreme Court dismissed the cassation appeal filed by a lawyer representing an employees' union without the individual client's specific power of attorney. Although the union's general authorization covered the client, the court held that the lawyer must also present the client's own mandate to act in their personal capacity. The appeal was rejected because the missing individual authorization constitutes a non-curable defect under the Civil Procedure Code.
