Now he's representing whistleblowers who claim the U.S. government has concealed non-human intelligence for decades. That sentence would have ended a career twenty years ago. Today it lands differently.

That is Sheehan's actual question. Not "are they real?" Not "what are they?" The legal question — the constitutional question — is who decided the American people didn't have the right to know, and under what authority they made that decision.

He raised the same question about Karen Silkwood's death. About the My Lai command chain. About the CIA's Central American networks. The subject changes. The architecture doesn't.

Daniel Sheehan holds three Harvard degrees: undergraduate, law, and divinity. That combination is not incidental. His legal philosophy is explicitly rooted in the Jesuit preferential option for the poor — the principle that moral systems are judged by how they treat the most vulnerable. He treats law as the instrument through which that judgment gets made in public, on the record, where it can be challenged.

He is now in his late seventies. He calls the UAP disclosure work the culmination of everything that came before.

UAP disclosure has moved. It crossed from tabloid speculation to Senate Intelligence Committee briefings. Congressional witnesses have testified under oath. The Pentagon has acknowledged craft it cannot identify or explain. Sheehan didn't chase that story. The story caught up with the framework he built.

The man who argued Karen Silkwood's case to the Supreme Court is now arguing that secrecy itself has become the crime.

My Lai happened on March 16, 1968. U.S. Army troops killed between 347 and 504 unarmed Vietnamese civilians. The Army suppressed it. A soldier named Ron Ridenhour forced it into the open with letters to Congress in 1969. The military justice system processed it down to a single man: Lieutenant William Calley, convicted in 1971, pardoned by Nixon shortly after.

Sheehan's engagement with the My Lai legal proceedings gave him a thesis he never abandoned. Institutions sacrifice individuals to protect systems. The prosecution of Calley was not accountability. It was containment. One man absorbs the charge. The command structure walks. The doctrine that ordered the operation goes unnamed and unpunished.

Command responsibility — the legal principle that superiors bear accountability for atrocities carried out under their authority — was established at Nuremberg. At My Lai, it stopped at a lieutenant. Sheehan watched that happen. It became the thread running through every major case he took afterward.

The pattern is not subtle. A system under pressure finds the lowest-ranking actor with traceable culpability. It prosecutes visibly. It protects invisibly. The institution survives. The individual serves the sentence.

He connected with the Pentagon Papers network through that period. He defended the Berrigan brothers — Catholic priests who burned draft records — arguing in court that a higher moral law can supersede statute. Courts mostly rejected that argument. Sheehan noted the rejection and kept the argument.

Karen Silkwood was a nuclear technician and union activist at a Kerr-McGee plutonium plant in Oklahoma. She died in a car accident in November 1974, on her way to meet a journalist with documents alleging safety violations. She had been found to be contaminated with plutonium days before she died. The circumstances of her death have never been fully explained.

Sheehan took the civil case. The central legal obstacle was federal preemption — the argument that federal nuclear regulation superseded any state tort claim. If Kerr-McGee could establish preemption, citizens could not sue nuclear companies in state court, regardless of what those companies did.

Sheehan built his counter-argument from nuclear physics upward. He combined radiological evidence, labor law, and constitutional preemption doctrine into a single litigation strategy precise enough to reach the Supreme Court.

In 1979, the Court ruled for Silkwood's estate. State tort claims against nuclear facilities were not preempted by federal law. The entire nuclear industry opened to civil accountability overnight.

That ruling is not famous. It should be. It changed what American citizens could do when a nuclear company harmed them. It came from a lawyer who had started his career defending draft resisters and working through My Lai's legal aftermath.

Sheehan did not stumble into nuclear accountability. He arrived at it by following the same question: who is protected when something goes wrong, and who pays the price?

The Christic Institute lawsuit is Sheehan's most consequential failure. It is also, arguably, his most consequential case.

In the mid-1980s, Sheehan filed a sweeping civil RICO lawsuit. The claim: that a CIA-connected "Secret Team" — a network of covert operatives, arms dealers, and drug traffickers — had run illegal wars across Central America for decades, operating outside congressional oversight or democratic accountability. The suit named specific individuals. It alleged a continuous criminal enterprise running from the Bay of Pigs through Iran-Contra.

The case was dismissed in 1988. The judge found the evidence insufficient. In 1992, the Christic Institute — the nonprofit law center Sheehan had built — was sanctioned one million dollars in defendant legal fees. That order destroyed the organization.

The Senate Kerry Committee report, published in 1989, confirmed CIA links to drug trafficking in the Contra supply network. The CIA's own inspector general confirmed related findings in 1998. The facts Sheehan had alleged — not all, but the structural core — were real.

They were confirmed too late. The case was already dead. The institution that built the case was already destroyed.

This is not a footnote. It is the hardest lesson in Sheehan's career, and he has not avoided it. The distance between being structurally right and evidentially sufficient is not a technicality. It is the distance between accountability and impunity. Sheehan reckoned with it. He rebuilt. He kept going.

What the Christic collapse also demonstrated: filing a large, structurally accurate lawsuit against powerful institutional actors, without sufficient documentary evidence in hand, can destroy the institution filing it. That lesson shapes how he approaches the UAP cases now.

After the Christic collapse, Sheehan founded the Romero Institute — named for Archbishop Óscar Romero, the Salvadoran bishop assassinated in 1980 while saying Mass, after years of advocating for the poor against state violence. The name is not decorative. Romero was killed because he refused to separate moral obligation from political reality.

Sheehan developed what he calls the Christic Theory: a systematic framework connecting evolutionary biology, consciousness studies, and constitutional law. The argument is that human legal and political structures cannot be understood in isolation from the larger questions of what consciousness is, what intelligence is, and what moral obligations follow from those answers.

Critics call this overreach. They are not entirely wrong. The framework is vast. It resists falsification at its cosmological edges. It asks law to carry metaphysical weight that courts will not acknowledge.

But the framework holds the cases together in a way that purely procedural accounts do not. My Lai, Silkwood, Iran-Contra, UAP — the connecting tissue is not coincidence or personal interest. It is a consistent claim about power, secrecy, and the corruption of knowledge. The Christic Theory is Sheehan's attempt to name that tissue explicitly, to give it theoretical structure, so it can be argued rather than merely felt.

His Jesuit formation is visible here. The preferential option for the poor is not a sentiment. It is an analytical tool — a way of asking who bears the cost of any system's choices, and whether those who bear the cost had any say in making them. Sheehan applies that tool to constitutional law the way his teachers applied it to theology.

Whether that synthesis holds is a genuine open question. What is not open is that it has produced fifty years of active legal work, two Supreme Court appearances, and a consistent record of identifying institutional concealment before the institutions admit to it.

UAP — unidentified aerial phenomena — is the government's current term for what it used to officially ignore. The term shift matters. The 2021 Office of the Director of National Intelligence report acknowledged 144 UAP incidents the U.S. military could not explain. The Senate Intelligence Committee held briefings. The Pentagon established the All-domain Anomaly Resolution Office. Congressional witnesses testified under oath in 2023 about direct knowledge of non-human intelligence programs.

Sheehan entered this space as legal counsel. He began representing individuals inside U.S. government — military and intelligence personnel — who claimed firsthand knowledge of concealed programs involving recovered non-human craft and biological material. He testified in congressional contexts. He filed legal demands for disclosure on constitutional grounds.

The legal argument he brings is not about the reality of UAP. It is about unauthorized classification — the claim that programs concealing this information from Congress and the public were established and maintained without legal authority. That secrecy, he argues, constitutes a seizure of public knowledge by an unaccountable executive apparatus. It is, in constitutional terms, a crime.

This is the My Lai argument. This is the Silkwood argument. This is the Christic argument, rebuilt with better evidence and a legal landscape that has shifted around it. The Senate has passed legislation requiring UAP disclosure. Multiple credible witnesses have gone on record. The Pentagon cannot explain what it has documented.

The subject is stranger than anything Sheehan argued before. The legal structure underneath it is identical to everything he argued before.

He is in his late seventies. He has lost major cases. He has watched organizations he built get destroyed by the legal costs of fighting powerful defendants. He continues.

The question he keeps returning to is not mysterious. It is the oldest question in democratic theory: who decides what the public is allowed to know, and what happens to a government that answers that question in secret, permanently, without consent?
