The legal issues involved in this case relate to the entitlement of a director to remuneration and reimbursement for expenses in the absence of any explicit agreement or provision in the company’s Articles of Association.

1. Directors’ Remuneration:
   According to company law, directors are not automatically entitled to remuneration unless it is expressly provided for in the Articles of Association, or there is a specific agreement to that effect. Since the Articles of Association of YEBA Limited are silent on directors’ remuneration, and there is no written agreement, Bala may face challenges in claiming the N2 million annual remuneration for the years 2015 to 2017. His claim would not be enforceable unless he can prove a precedent or implied agreement for such payments.
2. Reimbursement for Expenses:
   With respect to the N2 million reimbursement for travel expenses, Bala may have a stronger case. Directors are typically entitled to reimbursement for reasonable expenses incurred in the course of performing their duties, even if there is no formal agreement. If Bala can demonstrate that his travel expenses were necessary for attending board meetings and were incurred in the course of his duties, he may be entitled to reimbursement based on equitable principles or customary practice.
