Legal Rule:

• Proof of Debt: Courts must thoroughly investigate disputed debt amounts, including verifying payments made and ensuring claimed amounts are supported by evidence. Reliance on unsubstantiated claims is improper.
• Case Management: Proper case management requires identifying relevant issues, evaluating evidence, and making findings of fact. Failure to do so constitutes a fundamental flaw.
• Applicability of Interest and Penalties: The applicability of interest and penalties in a guarantee agreement depends on the specific terms of the agreement and relevant legal provisions. A bank's internal policies do not automatically override legal limits or contractual agreements.

Summary of Facts:

Ato Worku Genet (Applicant) disputed the amount of debt claimed by Oromia International Bank S.C. (Respondent) related to a bank guarantee agreement. The Applicant argued the amount was significantly less than the Respondent's claim and challenged the legality of the interest and penalties charged. The lower courts ruled in favor of the Respondent.

Decision of the Supreme Court:

The Supreme Court reversed the lower courts' decisions and remanded the case for retrial. The Court held that the lower courts failed to adequately investigate the disputed debt amount, relying solely on the Respondent's claims. The Court emphasized the importance of proper case management, including thorough investigation of evidence and factual findings. The Court outlined specific questions that the lower court must address on remand, including the exact amount paid by the Respondent under the guarantee, the applicable interest and penalty rates, and the legal basis for any remaining debt.
