For many businesses, transactions often begin long before lawyers draft agreements. A supplier delivers materials to a construction site, a project manager approves deliveries, invoices are issued, payments are made, and work continues. But when disputes emerge, one question often determines whether a claim succeeds: was there a formal written contract?
A recent High Court decision in Uganda has provided important clarity on that question, affirming that commercial obligations cannot always be avoided simply because parties failed to reduce their agreement into a single signed document.
In Jan Mohammed Enterprises Ltd. v. Prism Construction Ltd. (HCCS No. 0013 of 2017), delivered on July 6, 2026, Justice Harriet Grace Magala ruled that courts will consider the reality of commercial dealings, including evidence of performance, rather than allow businesses to escape legitimate obligations through technical arguments.
The decision carries significant implications for companies, suppliers, contractors, and anyone engaged in commercial transactions where business activity often moves faster than paperwork.
The dispute arose from construction works at Moyo Hospital between 2014 and 2015.
Jan Mohammed Enterprises Ltd supplied construction materials to Prism Construction Ltd valued at UGX 127.1 million. The supplier received only UGX 18 million, leaving an outstanding balance of UGX 109.1 million.
When the supplier sought recovery of the unpaid amount, Prism Construction challenged the claim.
The company argued that the arrangement had only been limited to UGX 20 million, supported by a postdated cheque. It further claimed that additional materials supplied beyond that amount were not authorized by company management.
Prism also questioned delivery notes that referred to “Prism” rather than the company’s full registered name and argued that the alleged agreement was unenforceable because it was not contained in a formal written contract.
The court rejected these arguments and found that the supplier had established a valid commercial relationship supported by evidence.
One of the most important lessons from the judgment is that a contract is not always defined by a single signed document.
Prism Construction relied on provisions of Uganda’s Contracts Act, arguing that agreements above UGX 500,000 must be in writing. However, the court distinguished between a formal contract document and evidence proving that an agreement existed.
Justice Magala found that commercial transactions can be demonstrated through a combination of records, including invoices, delivery notes, receipts, account statements, and payment histories.
The court emphasized that where a company receives goods, uses them, and makes partial payments, those actions provide strong evidence of an underlying contractual obligation.
The ruling reinforces a fundamental commercial principle: businesses cannot accept the benefits of a transaction and later reject responsibility simply because the paperwork was incomplete.
For suppliers, this provides reassurance that proper business records can protect their interests even where formal agreements are absent.
For buyers, it serves as a warning that accepting goods and services creates legal responsibilities regardless of internal approval processes.
The case also examined a common challenge in commercial disputes: whether employees or representatives had authority to commit a company.
Prism Construction argued that its site personnel had exceeded their authority when ordering additional materials.
The court disagreed, applying the principle known as the Indoor Management Rule, which protects third parties dealing with companies in good faith.
The principle allows outsiders to assume that a company’s internal approval procedures have been followed unless there is evidence suggesting otherwise.
In this case, evidence showed that a company director had introduced the supplier to the project team and allowed those officials to receive materials on behalf of Prism Construction.
By creating the appearance that these individuals had authority to act, the company could not later deny responsibility for their actions.
The ruling highlights an important governance lesson: internal company policies cannot automatically shield businesses from obligations created through their employees’ actions.
If companies have strict procurement limits, spending approvals, or delegation requirements, those restrictions must be clearly communicated to suppliers before transactions occur.
The court ordered Prism Construction to pay the outstanding UGX 109.1 million owed to Jan Mohammed Enterprises.
The supplier was also awarded interest at 18 percent per annum from the filing of the case until judgment, although the claim had sought a higher rate of 24 percent.
The court further awarded costs of the suit.
However, it declined to grant general damages because the claim had not been specifically pleaded in the original court documents.
This aspect of the judgment provides another important lesson for businesses: even where the underlying claim is strong, proper legal procedure remains critical.
The ruling offers practical guidance for both suppliers and companies operating in Uganda’s growing commercial environment.
For suppliers, documentation remains the strongest protection. Delivery notes, signed invoices, payment records, correspondence, and account statements can become critical evidence when disputes arise.
Businesses should not rely only on trust or verbal agreements, particularly for large transactions.
For companies purchasing goods and services, the decision highlights the importance of internal controls. Businesses must ensure that employees dealing with suppliers understand their authority limits and that those limits are clearly communicated externally.
A company cannot privately restrict an employee’s authority and then expect outsiders to know those restrictions without being informed.
The Jan Mohammed decision reflects a broader judicial approach toward commercial fairness.
Uganda’s economy continues to expand, with businesses increasingly operating through complex supply chains, construction projects, and service arrangements. In many cases, commercial activity begins before every legal document is finalized.
The court’s approach recognizes that commerce depends on trust, performance, and reasonable expectations.
The judgment does not reduce the importance of written contracts. Formal agreements remain the best protection against misunderstandings and disputes.
However, it confirms that businesses cannot use missing paperwork as a shortcut to avoid obligations created through their actions.
The message from the court is clear: in commercial dealings, substance matters. Companies that receive value from a transaction should expect to honour their commitments, whether those obligations appear in a formal contract or are demonstrated through the realities of business conduct.
