The insured or the pensioner may not be deprived of the pension or benefit unless by virtue of a disciplinary decision, provided that such deprivation does not exceed one quarter of the pension or benefit.

A judgment may not be passed to deprive the pensioner of the pension in accordance with the preceding paragraph unless for the actions carried out thereby prior to the termination of the service thereof.

No deduction or attachment of the due sums may occur in application of the provisions hereof against the pensioner or the beneficiaries thereof, unless for the payment of a judicially ordered alimony, for the payment of the sums due to the Government by the insured for reasons related to his job performance, or for the retrieval of the sums paid thereto without any right.

The sums deducted in such cases may not exceed one quarter of the pension. In case of competition, the priority shall be given to the alimony debt.
