A long-running legal battle over the release of United States government records concerning President Bola Ahmed Tinubu has taken another turn after a Washington-based political advisory and lobbying firm said its proposed court submissions have been formally docketed in the case.
Von Batten-Montague-York said the United States District Court for the District of Columbia has placed its Motion for Leave to File a Brief Amicus Curiae and a Supplemental Notice of Evidentiary Exhibits on the court docket in Greenspan v. Executive Office for U.S. Attorneys et al., Case No. 1:23-cv-01816-BAH.
The development does not amount to a finding that Tinubu committed a crime, nor does it mean the court has ruled that the allegations surrounding historical US investigations are established facts.
Instead, it adds another layer to a civil Freedom of Information Act (FOIA) dispute in which an American transparency advocate is seeking access to records held by US government agencies.
What has happened in the latest development?
According to Von Batten-Montague-York, its filings are now formally before the court after being entered on the federal docket.
The firm says it wants to participate in the proceedings as an amicus curiae, commonly described as a “friend of the court”. Such a participant is not ordinarily a direct party to a case but may seek to provide arguments or information that it believes could assist the court in deciding an issue.
The firm’s proposed intervention focuses heavily on the continuing dispute over privacy and public statements surrounding the records sought in the FOIA litigation.
Von Batten-Montague-York argues that statements made publicly by officials and associates of the Nigerian presidency should be relevant to the court’s consideration of privacy claims surrounding the records.
The firm has also pointed to what it describes as public comments about the controversy while President Tinubu’s legal team has argued in court that certain records should remain protected from disclosure.
However, docketing is an important procedural development rather than a judgment on the substance of those arguments.
The court still has to determine what weight, if any, should be given to the material and whether the firm’s request to participate in the case will ultimately be granted.
The case is not a criminal trial against Tinubu
One of the most important points for readers following the controversy is the distinction between the underlying allegations and the actual case before the Washington court.
The Presidency has repeatedly rejected descriptions of the proceedings as a criminal case against Tinubu.
In a statement issued in September, Special Adviser to the President on Information and Strategy, Bayo Onanuga, said the proceedings are a civil FOIA dispute concerning access to government records. He also stressed that the court has not found Tinubu guilty of criminal wrongdoing.
The distinction matters because a FOIA lawsuit generally concerns whether government agencies have complied with requests for records and whether exemptions under US law allow particular information to be withheld or redacted.
In this case, American transparency activist Aaron Greenspan filed the lawsuit after seeking records from several US agencies, including the FBI and DEA, relating to historical investigations involving Tinubu and other individuals. The lawsuit was filed in 2023 and remains pending.
Why are the FBI and DEA records significant?
The records at the centre of the dispute relate to historical investigations dating largely to the early 1990s.
Greenspan’s FOIA requests have sought records concerning Tinubu, including FBI materials and interview records connected with the period around 1992 and 1993. The litigation has also touched on records associated with a 1993 civil forfeiture proceeding involving approximately $460,000.
The wider controversy has its roots in claims concerning an alleged drug-trafficking and money-laundering investigation in the Chicago area.
Tinubu has denied wrongdoing, while the Presidency maintains that the current US proceedings should not be portrayed as a criminal prosecution.
The legal question now before the court is therefore much narrower than some headlines surrounding the controversy suggest: which government records must be disclosed under FOIA, and which can legally remain withheld or redacted?
Tinubu has already challenged the release of the records
The latest development comes after Tinubu’s legal team filed a response opposing the release of additional records.
Court filings reported in August show that Tinubu, who is participating in the litigation as an intervenor, argued that privacy protections under US law should continue to shield certain information in FBI and DEA records.
His lawyers asked the court to deny Greenspan’s effort to obtain additional material and to permit existing redactions and withholdings to remain in place. The filing was entered as Document 98 on August 28, 2026.
The legal team also argued that the existence of publicly available information about a person or an earlier proceeding does not automatically eliminate that person’s privacy interests in the contents of investigative files.
That argument is central to the dispute because the parties disagree over how much previously disclosed information affects the government’s ability to rely on privacy-related FOIA exemptions.
How the dispute reached this point
The current litigation dates back to June 2023, when Greenspan filed a FOIA lawsuit against several US government agencies.
The case initially involved requests to agencies including the Executive Office for US Attorneys, Department of State, FBI, Department of the Treasury and DEA. According to case records, the requests concerned records relating to Tinubu and other individuals.
The litigation subsequently became focused on whether agencies could refuse to confirm or deny the existence of certain records — a position commonly known as a Glomar response in US FOIA litigation.
In April 2025, Judge Beryl A. Howell ruled on important aspects of the dispute, including challenges to the agencies’ reliance on Glomar responses concerning certain records. The case continued, with disputes over remaining requests, redactions and privacy exemptions.
Tinubu later became an intervenor in the proceedings and has continued to contest disclosure of certain records.
What the latest filing could mean
The significance of the latest development is less about an immediate release of documents and more about the arguments that may now be placed before the judge.
Von Batten-Montague-York says the evidence accompanying its proposed amicus filing is intended to draw the court’s attention to public statements made by Nigerian officials and individuals associated with the controversy.
The firm contends that those public statements are relevant to the question of whether privacy arguments should carry the same weight when the controversy has already been publicly discussed.
That is an argument the court will have to assess under applicable US law. The filing itself does not establish that the firm’s interpretation will prevail.
Nor does its appearance on the docket automatically mean the judge has admitted every assertion contained in the submission as proven evidence.
A controversy now spanning politics, transparency and privacy
The case has increasingly developed beyond a simple disagreement between a FOIA requester and US government agencies.
It now involves competing interests: government transparency, individual privacy, the protection of law-enforcement records and the public interest in information concerning a sitting foreign head of state.
For the Nigerian government, the controversy carries obvious political implications because allegations relating to events from decades ago continue to generate international attention.
For Greenspan and transparency advocates, the case represents an attempt to determine how much information the US government can legally withhold from public access.
For Tinubu’s legal team, the central issue is the protection of information that they argue remains subject to legitimate privacy exemptions, even where aspects of the underlying controversy have previously entered the public domain.
What happens next?
The immediate question is whether the court will allow Von Batten-Montague-York to formally participate as an amicus and how the judge will treat the supplemental material it says has now been docketed.
The court must also resolve the broader FOIA dispute over the remaining FBI and DEA records.
That means readers should not interpret the latest docket development as a final ruling on the allegations against Tinubu.
The case remains active, and several outcomes are possible: the court could order the release of additional records, uphold some or all of the existing redactions, require further review by the agencies, or rule differently on particular categories of requested documents.
For now, the most concrete development is procedural: new submissions connected to the dispute have been placed on the federal court docket, giving the judge another set of arguments and materials to consider.
The underlying allegations remain contested, Tinubu continues to deny wrongdoing, and no criminal conviction against him has resulted from the Washington FOIA proceedings.
Timeline of the Tinubu FOIA dispute
2023: Aaron Greenspan files a FOIA lawsuit against several US government agencies over records relating to Tinubu and other individuals.
April 2025: The US District Court for the District of Columbia issues a significant ruling concerning agencies’ use of Glomar responses in relation to certain requested records.
2025: Tinubu participates in the litigation as an intervenor and challenges efforts to obtain additional records.
August 2026: Tinubu’s lawyers file a submission opposing the release of additional FBI and DEA records and argue that privacy exemptions should continue to apply.
September 2026: The dispute attracts renewed attention after the Presidency stresses that the proceedings are a civil FOIA records dispute rather than a criminal prosecution.
September 2026: Von Batten-Montague-York announces that its proposed amicus filing and supplemental evidentiary submission have been docketed in the case, adding another voice to the ongoing records dispute.
Bottom line
The latest development does not establish a new criminal case against President Tinubu. What it does show is that the dispute over access to historical US law-enforcement records remains active and is attracting additional legal and political arguments.
The next significant development will be the court’s treatment of the competing submissions and, ultimately, its determination of which records can be disclosed under US FOIA law.
