PLENA Enforced Disappearance & Political Detention Attestation
Receipts of what was known before someone disappeared. Built for the families of the disappeared, the international advocacy bodies working on their behalf, and the human-rights documentation infrastructure that requires verifiable evidence to function across decades.
Opening problem
Enforced disappearance — the detention, abduction, or deprivation of liberty by agents of the state or persons acting with state authorization, followed by refusal to acknowledge the deprivation of liberty or by concealment of the fate of the disappeared person — remains a pattern in dozens of countries. Mexico has documented more than one hundred thousand disappeared persons; Sri Lanka, Argentina, Chile, and other historical cases continue to generate inquiries decades after the events; contemporary cases proliferate in Syria, Belarus, Iran, Egypt, Bangladesh, Pakistan, Myanmar, Eritrea, and the Xinjiang Uyghur Autonomous Region.
The International Convention for the Protection of All Persons from Enforced Disappearance entered into force in 2010. The UN Working Group on Enforced or Involuntary Disappearances has documented cases since 1980. The International Committee of the Red Cross operates the Restoring Family Links program. Regional bodies — the Inter-American Commission on Human Rights, the African Commission on Human and Peoples' Rights, the European Court of Human Rights — adjudicate cases. National truth commissions in Argentina, Chile, Guatemala, Peru, South Africa, Sri Lanka, and elsewhere have spent decades attempting reconstruction.
The structural problem these institutions repeatedly encounter is evidentiary. The family of the disappeared person needs to demonstrate, often decades later, what was known immediately before the disappearance: who was the person's last contact, what was their last documented location, what political activities were they engaged in, which authorities had reason to detain them, what witnesses were present at the moment of disappearance. Ad-hoc affidavits accumulated over years, photographs that have faded or been lost, testimony of witnesses who have themselves been killed or displaced — the evidentiary base for advocacy is fragile and shrinks with time.
PLENA Enforced Disappearance & Political Detention Attestation is built to address this evidentiary fragility — not by adjudicating disappearance cases, replacing the UN Working Group or ICRC, or representing families in legal proceedings, but by producing the receipt layer that captures what was known before the disappearance, that survives the witnesses' own deaths and displacements, and that reads as authoritative to international bodies decades after the events.
This product is documentation infrastructure for the International Convention for the Protection of All Persons from Enforced Disappearance and for the broader human-rights documentation field. It is built for advocates who currently work with fragmentary evidence and who would benefit from receipts captured at the moment they were most reliable.
Five cases PlenaProof covers
For each case, three actors share the work: the at-risk individual (or, retroactively, the family) makes the declarations, named witnesses (community elders, professional associates, civil-society observers, designated source-country releasers) attest, and PLENA seals the four-artifact bundle across multiple independent archives. The captures are either proactive (before any incident, by individuals at risk) or retroactive (after a disappearance, by family and associates).
Last-Contact Witnessed Declaration
Captured proactively by individuals at risk (journalists, opposition figures, human-rights defenders, members of targeted communities) or retroactively by family members and associates after a disappearance has occurred. Documents the person's last documented activities, locations, contacts, and any specific threats received.
- Witnessed Activity Declaration. Sealed record of activities, contacts, and locations in the period before disappearance (proactive) or last known (retroactive).
- Sealed Contact and Location Evidence. Photographs, communications archives, location records, identified threats.
- Refresh Yearbook. For proactive captures — periodic re-attestation while the individual remains reachable.
- Multilingual Handover Packet. Drafted for the UN Working Group on Enforced or Involuntary Disappearances, ICRC, and regional human-rights bodies.
Detention Event Documentation
Where the family or associates witnessed the detention or have direct evidence of it — identity of the detaining authority, time and place, photographs, third-party witnesses, transit reports. Captured as soon as possible after the event while memory and physical evidence remain.
- Detention Event Declaration. Sealed account of the detention as witnessed or reconstructed from immediate post-event evidence.
- Sealed Evidence Packet. Photographs, identifying details of vehicles and uniforms, transit-route witnesses, dated documentation.
- Witness Network Attestation. Map of corroborating witnesses, with their own attestations captured while they remain reachable.
- Multilingual Handover Packet to UN WGEID and ICRC Restoring Family Links.
Family Standing and Authority Receipt
Receipt of which family members have standing to pursue inquiries on behalf of the disappeared person, what authority they hold to access information and make decisions, and any disputes among family members about that authority. Disappearance cases often span generations and create conflicting claims; this case captures the authority structure before disputes harden.
- Family Standing Declaration. Sealed statement of which family members hold standing and the basis for that standing.
- Sealed Authority Evidence. Documents establishing family relationship, power of attorney where applicable, court appointments.
- Refresh Yearbook. Reflects changes in family standing across years and generations.
- Multilingual Handover Packet. Releasable to advocacy bodies, truth commissions, and inheritance proceedings.
International Advocacy Handover Packet
Designed specifically for handover to the UN Working Group on Enforced or Involuntary Disappearances, the International Committee of the Red Cross Restoring Family Links program, regional human-rights bodies, and national or international truth commissions. Includes structured presentation of evidence calibrated to each body's evidentiary expectations.
- Advocacy Packet Declaration. Sealed cover statement of the case as the family wishes it to be advocated.
- Sealed Evidence Archive. All prior receipts bundled, organized by receiving body.
- Periodic Refresh. Updates as new evidence surfaces or as cases progress through inquiry bodies.
- Multi-Body Handover Templates. One packet per receiving institution, calibrated to each body's evidentiary standards.
Long-Term Search and Update Continuity
Receipt structure that survives the multi-decade arc of many disappearance cases: updates as new evidence surfaces, as witnesses provide retrospective testimony, as truth commissions or judicial proceedings produce findings. The artifact becomes the family's living evidentiary archive.
- Continuity Declaration. Sealed multi-year statement of inquiry status.
- Sealed Long-Term Archive. Bundled prior receipts plus any new evidence over time.
- Update Yearbook. Annual or trigger-driven re-attestation.
- Multilingual Handover Packet to successor advocacy and inquiry bodies. Drafted to remain readable when the original inquiry body has been superseded.

The 100-Year Operating Commitment
Adapted for the multi-decade arc of disappearance cases.
PLENA Enforced Disappearance & Political Detention Attestation is built on the multi-decade arc of disappearance cases. Many of today's open inquiries originate from events of the 1970s and 1980s; many of today's events will remain open inquiries in 2070. Where actually implemented and populated, the intended architecture replicates each artifact produced here across multiple independent archives and anchors it cryptographically to public records that do not depend on the continued existence of any single state or international body, and verifiable offline by anyone holding the cryptographic keys. The receipt created today must be readable when the witnesses, the advocates, the truth commission, the regime, and the technical platforms that created it have all passed.
Why this differs from existing human-rights documentation platforms
Several platforms collect human-rights documentation — eyeWitness to Atrocities (International Bar Association), Hala Systems, Bellingcat methodology, and the open-source-intelligence ecosystem more broadly. These platforms focus on capturing photographic and video evidence of atrocities, often in real time, with chain-of-custody guarantees for prosecution. PLENA Enforced Disappearance & Political Detention Attestation is a different product addressing a different problem.
Family-controlled
The receipt is held by the family or designated advocates, not by the documentation platform or a prosecuting body.
Preemptive capture
Built to be created by individuals at risk before any incident, not only by witnesses after one.
Long-arc design
Built for the multi-decade time horizon of disappearance cases rather than the prosecution-focused short arc of atrocity documentation.
Witness-network architecture
The receipt explicitly maps the network of associates and witnesses who can corroborate.
Multi-body handover
Designed for multiple international and national receiving institutions rather than one.
Survives the witnesses
Captured when memory and physical evidence are most reliable; preserved when those who knew the disappeared are themselves gone.
PLENA Enforced Disappearance & Political Detention Attestation complements atrocity-documentation platforms for any case that involves both, but the two layers serve different inquiries.
Existing instruments this complements
- International Convention for the Protection of All Persons from Enforced Disappearance (CED, 2006, in force 2010)
- Inter-American Convention on Forced Disappearance of Persons (1994)
- Declaration on the Protection of All Persons from Enforced Disappearance (UN, 1992)
- Rome Statute (defining enforced disappearance as a crime against humanity)
- Geneva Conventions (missing persons and protection of family members)
- UN Working Group on Enforced or Involuntary Disappearances methods of work
- International Committee of the Red Cross Guidelines on the Use of Personal Data in Restoring Family Links
What this does not do
PLENA Enforced Disappearance & Political Detention Attestation does not locate disappeared persons. It does not adjudicate disappearance cases or assign criminal responsibility. It does not transfer evidence to prosecuting bodies without the family's consent. It does not replace forensic investigation, DNA matching, or remains identification. It does not represent families in legal proceedings or appear as a party in international human-rights cases. It does not constitute legal advice. It does not provide protection to individuals at risk — the receipt is documentation infrastructure, not personal security.
Languages and the human-reviewer queue
This page launches in PLENA's 8 live languages. The languages most central to current disappearance populations — Spanish (Latin America), Arabic (Syria, Egypt, Yemen, Saudi Arabia, Sudan), Russian (Belarus, Chechnya, Russia, Central Asia), Mandarin (Xinjiang context), Bengali (Bangladesh, Rohingya), Tagalog (Philippines), Turkish (Turkey, Kurdish populations) — are largely in the launch set. Sinhala, Tamil, Burmese, Tigrinya, Pashto, and Farsi remain in the human-reviewer queue.
Uyghur is held entirely for human translator capture. Machine-translation model coverage of Uyghur is too thin, and the population at stake is too vulnerable to risk machine error. Uyghur translators particularly welcome — contact hello@joinplena.com.
