Brasília, August 3, 2026
The Articulation of Indigenous Peoples of Brazil (APIB), a national organization composed of indigenous organizations from different regions of the country, alerts the international community to the escalating threats to the territorial rights of indigenous peoples in Brazil.
This week, the Federal Supreme Court (STF), the highest body of the Brazilian judiciary, will resume decisive landmark hearings on the so-called “Time Frame Thesis” (“Marco Temporal”) and Federal Law No. 14,701/2023. At the same time, proposals are moving forward in the National Congress to suspend already completed land demarcations and weaken the legal framework governing the recognition of Indigenous lands.
This scenario represents a legal and political conflict marked by a coordinated offensive that threatens hundreds of Indigenous Peoples, increases insecurity and violence against Indigenous communities, and undermines the protection of biodiversity and efforts to address the climate crisis.
The “Time Frame Thesis” is a legal doctrine according to which Indigenous Peoples would only be entitled to the demarcation of lands they were physically occupying on October 5, 1988 — the date the current Brazilian Constitution was enacted — or lands for which they could prove the existence of an ongoing legal dispute or persistent conflict on that date.
This thesis disregards the fact that countless Indigenous Peoples were expelled from their ancestral territories before 1988 due to state actions, economic ventures, armed violence, persecution, forced removals, and historical processes of colonization. In many cases, these communities were unable to seek judicial protection or safely return to the lands from which they had been removed.
In 2023, when ruling on the case involving the Xokleng People of the Ibirama-Laklãnõ Indigenous Territory, the Federal Supreme Court (STF) held that the Time Frame Thesis was unconstitutional. The Court recognized that Indigenous Peoples’ rights to their traditional lands are original — that is, rights that predate the very formation of the Brazilian State — and that the demarcation process merely identifies and officially declares a pre-existing right.
Despite this ruling, the National Congress enacted Federal Law No. 14,701/2023, which attempted to reinstate the Time Frame Thesis and introduced several restrictions on the demarcation, protection, and exclusive use of Indigenous Lands. The law was passed without taking into account all the impacts on Indigenous Peoples, territories, and the environment, as repeatedly pointed out by the Indigenous organizations.
The Time Frame Thesis was rejected, but its effects persist.
In December 2025, the Brazilian Federal Supreme Court (STF) once again formally rejected the Time Frame Thesis. However, it upheld significant portions of Law No. 14,701/2023 and established rules that may delay — or even prevent — the effective restitution of Indigenous ancestral territories to their rightful peoples.
Among these measures are the expansion of compensation for non-Indigenous occupants, allowing such occupants to remain on Indigenous lands until compensation is payed, permitting the allocation of alternative territories, creating new administrative obstacles to the demarcation process, and imposing sanctions on Indigenous communities that undertake the reoccupation (“retomadas”) of their traditional territories.
APIB refers to this process as the material deconstitutionalization of Indigenous rights. Although Article 231 of the Brazilian Constitution remains formally in force, its effectiveness is being undermined by judicial interpretations and administrative rules that make it increasingly difficult for Indigenous Peoples to secure recognition and protection of their traditional territories.
In practice, the restitution of traditional lands is no longer a clear priority; budgetary constraints and administrative delays now condition the demarcation process; non-Indigenous occupants receive expanded procedural protections; and the Indigenous communities’ efforts to reclaim their ancestral territories after decades of state inaction are increasingly treated as unlawful acts.
It is unacceptable for ndigenous Peoples to be penalized for the Brazilian State’s own, failure to comply with the constitutional five-year deadline — counting from the promulgation of the 1988 Brazilian Constitution— to complete the demarcation of all Indigenous lands.
Appeals related to General Repercussion Theme No. 1,031— the procedural mechanism created by the Federal Supreme Court to organize and group cases addressing the same legal or constitutional question — and the constitutional challenges to Law No. 14,701/2023 are expected to be heard jointly by the STF. The hearing is scheduled to take place between August 7 and 18, 2026, initially through the Court’s virtual plenary system.
The Court’s decision may have far-reaching consequences for hundreds of Indigenous land demarcations and territorial disputes across Brazil. APIB advocates that the case should be heard in the STF’s in-person plenary chamber, ensuring public scrutiny and the effective participation of Indigenous peoples.
There is also growing concern that exceptional measures — such as granting an alternative area or provinding financial compensation instead of restoring the traditional territory — might come to be treated as standard solutions in Indigenous land demarcation proceedings.
Precedents from the Inter-American Human Rights System establish that alternative remedies may only be considered in truly exceptional circumstances, supported by compelling evidence and subject to effective consultation with, and the consent of the affected Indigenous People. The primary remedy must remain the restitution of the traditional territory.
Another serious setback is the attempt to equal indigenous land reclaims (“retomadas”) with ordinary property invasions or trespassing.
Retomadas are collective processes through which Indigenous Peoples return to portions of their traditional territories following expulsions, violence, and decades of state neglect. They cannot be analyzed according to a purely civil or commercial logic of property. The rules upheld by the STF allow for expedited evictions, police operations, and administrative sanctions against Indigenous communities that undertake land reclaims. Among the sanctions is the possibility of moving the respective demarcation process to the end of the administrative queue.
Punishing an Indigenous community for attempting to return to the territory from which it was historically removed means shifting the consequences of state violence and inaction onto the victims.
The situation of the Aldeia Velha Indigenous Territory, home to the Pataxó People, in the municipality of Porto Seguro, in the state of Bahia, demonstrates that the effects of the Time Frame Thesis are far from abstract.
Although the territory completed the administrative demarcation process and has been ratified by the federal government, a legal dispute initiated by private interests has come to threaten the continued presence of Indigenous families across a substantial portion of the territory.
Arguments related to Law No. 14,701/2023 and the “Time Frame Thesis” were used to challenge the territory and justify an eviction order against approximately 650 families, which corresponds to about 2,000 Indigenous people. The disputed area represents more than half of the officially demarcated Indigenous territory.
The territory includes homes, a school, a health clinic, archaeological sites, mangrove ecosystems, and preserved areas of the Atlantic Forest. The attempt to remove the Pataxó people from their ancestral territory is taking place in a region marked by intense real estate speculation and the rapid economic appreciation in the value of coastal land.
The case illustrates a particularly dangerous consequence of the Time Frame Law: allowing companies, landowners, and other private interests to reopen disputes over Indigenous territories that have already undergone technical studies, administrative recognition, and formal ratification.
Thus, not even the formal conclusion of the demarcation process has been sufficient to guarantee territorial security for the communities.
A similar situation affects the Manoki Indigenous Territory in the state of Mato Grosso, where the territorial expansion process has likewise been challenged based on grounds of the absence of Indigenous occupation of the relevant area in 1988. These cases demonstrate that a legal doctrine previously declared unconstitutional continues to be invoked to suspend actions by the Executive Branch and threaten already-recognized territories.
The offensive is also advancing in the Brazilian National Congress:
Legislative Decree Bill No. 717/2024 seeks to annul the presidential ratification of the Toldo Imbu and Morro dos Cavalos Indigenous Lands in the state of Santa Catarina. Furthermore, it aims to suspend key provisions of Decree No. 1,775/1996, which regulates the administrative demarcation procedure of Indigenous lands in Brazil.
The bill has already been approved by the Federal Senate, and its expedited legislative procedure was approved by the Chamber of Deputies, allowing it to be submitted directly to the plenary without going through the relevant standing committees. Since it is a legislative decree bill, its eventual final approval will not require presidential sanction.
The threat, therefore, is not limited to these two territories. The suspension of Decree No. 1,775/1996 would undermine the legal framework used to identify, demarcate, and recognize Indigenous lands throughout the country, creating a ripple effect on demarcation proceedings at various stages.
Brazil is thus facing simultaneous attacks on Indigenous land demarcation through both legislative and judicial branches.
Indigenous territories are not merely physical spaces. They guarantee the collective existence of Indigenous Peoples, the transmission of knowledge, languages, and cultural practices, as well as food security, spirituality, self-determination, and the continuity of future generations.
The demarcation of Indigenous lands is also one of the most effective measures for curbing deforestation, protecting biodiversity, and addressing the climate emergency.
The Inter-American Court of Human Rights, in its Advisory Opinion No. 32/2025 on the Climate Emergency and Human Rights, recognized the particular vulnerability of Indigenous Peoples in the face of the climate crisis, the crucial role of their territories in conservation and climate change mitigation, and the States’obligation to provide them with enhanced protection.
In this context, territorial demarcation of Indigenous lands must be understood simultaneously as a historical redress and as a measure to protect life, self-determination, biodiversity, and the climate.
Weakening Indigenous territorial rights means facilitating the spread of land grabbing, the illegal exploitation of natural resources, deforestation, mining, predatory agribusiness, and real estate speculation.
It also means putting Indigenous peoples in isolation and those in initial contact at risk, as their territories remain vulnerable to invasions, wildfires, deforestation, and forced contact.
Call to the International Community
Given the gravity of the situation, APIB calls upon States, multilateral organizations, international human rights mechanisms, financial institutions, foundations, civil society organizations, and allies of Indigenous peoples to:
- closely monitor the trial scheduled for August 2026 and its effects on Indigenous territorial rights;
- express concern over any judicial decision or legislative measure that weakens the protection established by Article 231 of the Brazilian Constitution;
- advocate for the restitution of traditional territory as a priority obligation of the Brazilian State;
- reject the criminalization of land reclaiming efforts (“retomadas”) and of Indigenous human rights defenders;
- demand respect for the right to consultation and to free, prior, and informed consent (FPIC);
- monitor the progress of Legislative Decree Bill (PDL) No. 717/2024 and other legislative initiatives aimed at annulling Indigenous land demarcations or weakening the demarcation process;
- support the physical, legal, and political protection of threatened Indigenous communities and leaders; and
- ensure that financing, investments, and supply chains are not linked to the invasion, exploitation, or legal contestation of Indigenous territories.
The international community cannot treat events in Brazil as an exclusively domestic matter. The country has both constitutional and international obligations to protect Indigenous peoples and their territories.
Although the Time Frame Thesis was declared unconstitutional, its underlying rationale continues to be used to halt demarcation processes, criminalize Indigenous communities, reopen disputes over territories that have already beem officially recognized, and protect private economic interests.
APIB reaffirms that Indigenous Peoples’ original rights cannot be subject to an arbitrary date, traded in exchange for other territories, or conditioned upon payments compensating those who benefited from expulsions and land titlings promoted by the State itself.
There is no solution to the climate crisis without Indigenous peoples. There is no protection of biodiversity without securing our territories. And there is no democracy as long as the constitutional rights of Indigenous peoples remain subject to setbacks.
The Indigenous movement’s response will continue to be mobilization, advocacy, and resistance.
Our time frame is ancestral. We have always been here.
