A commercial arbitration in Paris spent years going through one man's bank records. What it found didn't stay in Paris.

Leno Adesanya's company sued Nigeria for $400 million. He lost. A three-member arbitration tribunal under the International Chamber of Commerce delivered its final award on September 16, rejecting the claim, ordering Adesanya's Sunrise Power and Transmission Company to repay Nigeria roughly $11.8 million in legal costs. Sunrise's claim traced back to a disputed 2003 build-operate-transfer award for the Mambilla hydropower project. Nigeria argued the Federal Executive Council never actually authorised it. The tribunal agreed.

That's the small story.

Here's the bigger one. To resolve the claim, the tribunal had to trace where Adesanya's money went. It went to a lot of places.

$500,000 moved from Adesanya's China Castle Investments account to a US account belonging to Jennifer Douglas, then the wife of Vice President Atiku Abubakar, four months before Mambilla's contract was awarded. Adesanya called it a foreign-exchange transaction on Atiku's behalf. The tribunal found the explanation unsupported by documents or witnesses, and flagged it. $1.74 million moved to Abubakar Dasuki, son of then National Security Adviser Sambo Dasuki. Adesanya called that one a loan. He could never produce a signed agreement. Smaller payments moved to people connected to Olu Agunloye, the power minister who signed the contract, to Abdullahi Yola, then solicitor general, and to Dere Awosika, then a permanent secretary. Former Attorney General Abubakar Malami got the sharpest words in the whole award. The tribunal found he kept an "inappropriate relationship" with Adesanya, and stood to collect a cut of a 2020 settlement.

The tribunal didn't call all of it bribery. Careful, on purpose. For several payments, it said plainly it couldn't prove what the official did in return. Former officials, their relatives, and people around them. Payments stretching back two decades. Again and again, the money travelled through somebody else. A wife. A son. An aide. An intermediary. A company.

None of this is the first time a foreign process has done the finding Nigeria's own institutions didn't. Between 1994 and 2004, a consortium of four companies, including a Halliburton subsidiary, paid $180 million in bribes to Nigerian officials to win $6 billion in gas contracts. Three former heads of state were named. So were former ministers and NNPC officials. The bribe-givers were convicted. Companies were fined. Individuals went to prison, in Houston, in Paris. Not one Nigerian official who received the money was ever convicted at home. That case is now more than two decades old. It's still the reference point Nigerians reach for when a scandal this size breaks, because it's still, functionally, unresolved on this side of the border.

Which is the shape worth watching here. Nigeria's EFCC has now set up a team, supervised personally by chairman Ola Olukoyede, to work through the Mambilla award. Sources say Atiku and Douglas may be invited for questioning, in the commission's own words, "in the coming days or weeks." That's the commission's own timeline, not a court's. Malami is already on trial, separately, over an unrelated N8.7 billion case involving him, his wife, and his son. That trial has been running for months. It hasn't concluded.

So the test isn't whether the EFCC opens a file. It already has. The test is whether opening it produces something the Halliburton case never did on Nigerian soil, a conviction, a forfeiture, a consequence that lands on the person who received the money and not just the company that sent it.

For someone without a former vice president's number in their phone, the comparison isn't abstract. A trader flagged for a suspicious transfer can have an account frozen the same day, no tribunal required, no committee formed first. A young man questioned over a stolen phone can spend weeks in custody before anyone reviews his file. The system that needs "coming days or weeks" to decide whether to invite a former vice president for a conversation is the same system that, for people without his connections, decides in hours.

Malami himself is a useful reminder that this isn't a one-off entanglement. He served as Attorney General from 2015 to 2023, one of the longest tenures the office has had. Eight years is long enough to build the kind of relationships a tribunal in Paris can later describe as "inappropriate." It's also long enough that a single ICC award naming him is unlikely to be the last document that does.

One tool the EFCC has used before doesn't require a criminal conviction at all. Non-conviction-based forfeiture lets the commission go after assets tied to unexplained wealth without first proving a crime beyond reasonable doubt, the standard route Nigeria used to recover a portion of the Abacha loot decades after his death, long after any prosecution of the man himself became possible. If the criminal case against Malami and whoever else the EFCC decides to pursue moves slowly, that route stays open regardless. Whether the commission uses it here is its own test of intent.

The EFCC has set up a team. The commission says it is now working through the award. The question is what happens after the reading.

A Paris tribunal handed Nigeria a paper trail twenty years in the making. The EFCC has it now. The next clock is Nigeria's.
