Except as is otherwise provided in this article, a claim shall be instituted by the filing of notice with the clerk. In accordance with rules promulgated by the court, each claim shall be considered by the court as a whole, or by a judge sitting individually, and if, after consideration, the court finds that a claim is just and proper, it shall so determine and shall file with the clerk a brief statement of its reasons. A claim so filed shall be an approved claim. The court shall also determine the amount that should be paid to the claimant, and shall itemize this amount as an award, with the reasons therefor, in its statement filed with the clerk. In determining the amount of a claim, interest shall not be allowed unless the claim is based upon a contract which specifically provides for the payment of interest.
