Post No Debit on a State's Accounts: What the Federal High Court's Interim Order in the Gamji and Osun Arbitration Dispute Does and Does Not Decide

On 4 October 2026, Nigerian outlets reported that the Federal High Court in Lagos has ordered commercial banks to place a "Post No Debit" restriction on accounts operated by the Osun State Government. The order was made by D.E. Osiagor J in Suit No. FHC/L/CS/1233/2026, on an application by Gamji Nigeria Company Limited, and it is tied to an arbitral award of 24 July 2026. The headline figure is $13,924,343.32 plus ₦157.5 million. But the single most important word in the story is "interim". This article explains what was reported, what was not decided, and the legal ideas a student or young lawyer needs to read the story correctly.

What happened?

According to the reports, Gamji applied to the Federal High Court for a preservation order after, it says, the State Government did not pay the award within the time allowed. The court granted an interim order directing the financial institutions cited in the application to restrict debits on the State Government's accounts so as to preserve the sums covered by the award, pending the hearing of Gamji's motion on notice. The banks named in the application include Guaranty Trust Bank, Access Bank, First Bank, Zenith Bank, United Bank for Africa, Ecobank, Fidelity Bank, Stanbic IBTC, Sterling Bank, Union Bank and Wema Bank, among others. Gamji was represented by Yunus AbdulSalam, SAN. The court adjourned the matter to 22 October 2026 for hearing of the motion on notice.

Background: the contracts and the arbitration (Gamji's account)

The following background comes from the affidavit filed by Gamji, as reported. It is the company's account, not a finding of any court.

Gamji says the Osun State Government awarded it two contracts in June 2017 for water infrastructure works in Ilesa West Local Government Area, to be financed through an Islamic Development Bank loan arranged through the Federal Ministry of Finance. It says the initial values were about $15.98 million (Slot 1, transmission mains and booster pump stations) and about $9.70 million (Slot 2, water reservoirs), and that design changes, a wider scope and variation orders later raised them to about $20.24 million and about $10.95 million. It says about 93 per cent of the works were done by October 2023 and that a Substantial Completion Certificate was issued on 14 November 2024.

Disagreements followed over extensions of time, price adjustments and increased costs. Gamji says its claims were rejected and mediation efforts did not resolve them, so it issued a notice of arbitration on 3 April 2025. It says the State accepted the process and nominated an arbitrator, and that a preliminary meeting was held in Lagos on 15 May 2025. Gamji says the tribunal delivered its final award on 24 July 2026, directing the State Government to pay $13,924,343.32 and ₦157.5 million described as reimbursable arbitration fees, with interest at 20 per cent a year on any unpaid portion after the compliance period. The compliance deadline, Gamji says, expired on 24 August 2026 without payment.

The key issue: preserving funds before enforcement

An arbitral award is a decision of a private tribunal. It does not collect itself. If the losing party does not comply, the winning party generally has to go to court to have the award recognised and enforced. That process takes time, and a creditor's fear is that the money may be moved or spent in the meantime.

This is where a preservation order comes in. A "Post No Debit" restriction is an instruction to a bank not to allow debits on an account. A preservation order of this kind does not say the creditor is right. It holds the money still, so that the court's later decision, whichever way it goes, is not rendered useless. That is why the order here is described as interim and as lasting until Gamji's motion on notice (a motion served on the other side, who gets to respond) is heard.

What the law says

The Arbitration and Mediation Act 2023 (AMA) is the main statute. According to published commentary on the Act, section 57 provides that an arbitral award is recognised as binding and, on written application to the court, is enforced by the court, subject to section 57 and section 58. Section 58 lists the limited grounds on which recognition or enforcement may be refused. The Act defines "court" (section 91(1), as described in the commentary) to include a State High Court, the High Court of the FCT and the Federal High Court. The AMA also created an Award Review Tribunal for Nigeria-seated arbitrations, with set-aside grounds in section 55(3), according to the same commentary.

Two cautions. First, the reports do not say which provisions Gamji relied on for the preservation order, whether the award has already been registered or recognised by a court, or why the Federal High Court was the chosen forum. Those answers are in the originating processes and the order itself, which have not been seen for this article. Second, the AMA references here come from published legal commentary, not from a reading of the Act's official text, so anyone citing the sections should check them against the Act.

What the court did

On the reports, the court granted a preservation order of interim injunction, directing the cited financial institutions to place a Post No Debit restriction on the State Government's accounts for the preservation of the sums of $13,924,343.32 and ₦157.5 million, towards the liquidation of the 24 July 2026 award, which the order describes as due and enforceable. TheNigeriaLawyer reports that the restriction applies to the extent necessary to preserve those sums. Some headlines describe the order as freezing the State's accounts. The more careful reading, on the reports, is that it is aimed at preserving funds up to the award amounts. The reports do not explain how the banks will apply it in practice.

What the court did not decide

This is the part that early headlines can blur. The reports say the order is interim and that it is not a final determination of any substantive challenge the Osun State Government may raise against the award or against Gamji's enforcement proceedings. So the court has not decided that the award is valid, that the State must pay, or that the award cannot be challenged. It has not yet heard the State on the motion on notice. I did not find a response from the Osun State Government in the reports reviewed, so its position is unknown.

Why it matters

For law students, the story is a clean lesson in three different stages that are easy to confuse: the award (the tribunal's decision), recognition and enforcement (the court process that gives the award the force of a court-backed obligation), and interim preservation (a protective step taken while the main questions are still open). A report that a court has "frozen" accounts says something about the third stage only.

For practitioners, it shows that courts can be asked to act early to protect an award creditor, and that the respondent's real opportunity to be heard arrives at the motion on notice. It also touches a sensitive point: the respondent is a State Government, and public funds are involved. The reports do not discuss whether any special rules on public funds were argued, and this article does not speculate.

Practical implications

For parties holding an award, the story illustrates the value of acting quickly to preserve assets while enforcement is pursued. For parties against whom an award has been made, including public bodies, it shows that non-payment can invite protective orders and that the available responses, including any challenge to the award, will be tested in court. For banks, an order of this kind creates immediate operational obligations on the accounts it covers, subject to its terms. For the public, the key point is restraint in reading the news: an interim order is a pause button, not a verdict.

Key takeaway

A preservation order protects the possibility of enforcement; it does not decide whether enforcement is justified. The next date to watch is 22 October 2026, when the court is due to hear the motion on notice.
