On 16 September 2026, Prime Minister Nyam-Osoryn Uchral dismissed his justice minister, Sainbuyangiin Amarsaikhan, saying the situation within the justice and internal affairs sector had reached "a critical point" (AKIpress, reporting Montsame and Zogii.mn). Six days later, parliament swore in Ganzorigiin Temüülen: an MP who made his name by resigning from government over the Oyu Tolgoi copper mine. Temüülen arrived with a purge order to execute and a prison service still run by the men his predecessor had fought. He also arrived, on his own published asset declaration, as the 100% owner of a construction company. Three weeks into the job, he was urgently asking parliament to legislate against developers who take buyers' money for apartments that do not exist.
Before the dismissal, the leadership of the Court Decision Execution Agency — the prison and enforcement service — held a press briefing against its own minister, and Amarsaikhan in turn publicly aired what he called serious cases connected to that leadership (reported by Docx.mn, October 2026). The Prime Minister ended the fight by removing the minister, and ordered the removal of all senior and mid-level executives of the ministry's organisations implicated in the incident, stating that the truth about all past issues must be established (AKIpress, September 2026; Mongolia Weekly, 28 September 2026). Three claims from that fight exist only as allegations:
At their briefing, agency head Brigadier General A. Namsamand and fellow leaders stated that Amarsaikhan had appointed even his own driver's wife to a director-level post, and that officials who refused his appointment demands faced abuse and pressure; camera footage was also said to be circulating showing the minister sending his own people to pressure a person to delete recordings (Gerelnews.mn, September 2026, summarising the briefing). Decode Mongolia has not verified this claim; it is published as reported.
Mongolia Weekly (28 September 2026) reports that Amarsaikhan accused former Prime Minister Gombojavyn Zandanshatar of conspiring with law-enforcement officials over illegal mining and of orchestrating a campaign to discredit him. Zandanshatar denied the allegations as political retaliation over his own dismissal of Amarsaikhan in 2025, and Mongolia Weekly notes the claims remain unproven. Decode Mongolia has not verified this claim; it is published as reported.
Docx.mn (October 2026) reports that before his dismissal Amarsaikhan publicly aired "serious cases" he said were connected to the leadership of the Court Decision Execution Agency — the same leadership that had briefed against him. The source does not specify the content of those cases. Decode Mongolia has not verified this claim; it is published as reported.
Temüülen's record before the ministry is documented in his parliament biography. Born on 10 January 1981 in Ikh Tamir, Arkhangai, he was educated at Dickson College in Canberra and American University in Washington, D.C. (BA 2003; master's 2005). He joined the Mineral Resources Authority in 2006, rose to head its contract department, and headed the working group that produced the 2009 Oyu Tolgoi investment agreement. He was deputy director of Erdenes Mongol from 2009 to 2014, sat on the board of Oyu Tolgoi LLC from 2013 to 2015, and served as Deputy Minister of Mining in 2014–2015. In 2015 he resigned in protest at the Oyu Tolgoi "Dubai agreement," arguing it would delay Mongolia's dividend for years. He then presided over the MPP's Social Democratic Youth organisation (2015–2020) and was elected to parliament in 2016, 2020 and 2024, chairing the Budget Committee (2022–2024) and the Security and Foreign Policy Committee (2024–2026). The resignation reads both ways — a documented protest, and the act that converted a technocrat into a politician months before his first election. No source checked alleges any improper benefit to him from the 2009 work or the 2015 resignation.
His 2025 asset declaration, as summarised from the IAAC filing by UIH.mn, lists: Euroconstruction LLC at 100%; TTEM LLC at 34%; Hanburgedei LLC at 20%, with a declared value of ₮286,675,990 — the company runs the Hanburgedei department store and supermarkets; and Yarlag LLC, for which the declaration display gives no percentage while UIH's own analysis of the same declaration gives 20%. That discrepancy is unresolved on the face of the state's own publication system. Two further entries, Harte Gold Corp — a Toronto-listed gold name — and Chemostemics LLC, are entered at ₮0.
The same declaration values his real estate at ₮2,218,030,000 and his vehicles at ₮1,229,259,000, with savings of ₮94,473,000, against declared income of ₮75,714,000 in 2025 (₮62,328,000 in 2023; ₮69,774,000 in 2024). The real estate and vehicles together total ₮3,447,289,000 — roughly 45 years of his declared 2025 income. That ratio is not an allegation — declarations include family assets and pre-office wealth, and his companies predate his ministry — but no published source checked explains the acquisition history. No court case, IAAC proceeding or sanction naming Temüülen personally was found in the sweeps behind this piece, and no tender, contract or fund flow naming any of his companies was located either. Both statements describe the record searched, not a clearance: the contract register could not be checked in bulk.
In October 2026 the minister urgently submitted draft amendments to the Law on State Registration of Property Rights aimed at apartment-sales fraud — double contracts, presales of unregistered units, developers who took buyers' money — citing 2,173 unfinished apartments nationwide and proposing a per-unit registration code so a unit can never be sold twice (Docx.mn, reporting the minister's own press statement, around 21 October 2026). The minister sponsoring emergency legislation to police developers' presales is the 100% owner of a construction company. No source checked states whether Euroconstruction LLC has unfinished units, presale contracts, or any exposure to the 2,173-unit problem. Whether his own company stands inside or outside the problem his bill polices is the central unanswered question in this file, and it is put to him below.
Ergelt.mn (September 2026) reports that the minister's wife, S. Enkhzul, holds interests in Hanburgedei LLC and TTEM LLC together with her older sister, S. Ölziikhutag, and that Ölziikhutag's husband, Ch. Tsogbayar, has headed the State Reserve Department of the National Emergency Management Agency since 2017. The minister's father, Ch. Ganzorig, is reported to be a former Erdenet executive (Newsroom.mn). No wrongdoing by Tsogbayar is alleged in the source, and Decode alleges none: the line belongs on the map because the minister's extended family includes the long-serving head of the state reserves apparatus — a procurement and stockpile body — while he now runs the system that investigates procurement crime. Registry extracts that would settle the reported shareholdings have not yet been obtained.
The removals the Prime Minister ordered in September stalled. Docx.mn reported that as of around 6 October 2026, A. Namsamand was still in post, attending the Justice Standing Committee, with the removals held up on the legal point that removal authority sits with the Justice Minister. On 14 October, however, Temüülen stated publicly that under the Government Law a minister may appoint and dismiss only deputy heads of subordinate agencies, and that the power over agency heads — he named the Court Decision Execution Agency and the National Police Agency — rests with the Cabinet Secretariat (GoGo.mn, 14 October 2026). The new minister was thus on record narrowing his own authority over the purge's two most sensitive posts. Whether Namsamand has since been removed was not established. Inside his own ministry he has appointed an acting State Secretary, three department heads and two advisers, stating that appointments would follow a merit principle, "not political affiliation or personal connections" (Niitlel.mn, October 2026); no connection between any appointee and his family or companies was found. His first public controversy in the seat, over mid-October traffic-rule changes (eGov.mn), carries no integrity allegation.
On 2 September 2026, philosopher S. Molor-Erdene was detained under Article 19.9 of the Criminal Code — "undermining national unity," carrying five to twelve years — after stating on a Facebook talk show that "Mongolians" as a people do not exist and that Chinggis Khan was not Mongol (Great State Mural podcast, Agula Media, 16 September 2026). The programme criticised the then justice minister for deploying legal power against critics. Decode searched for a dismissed court case behind the removal, in English and Mongolian sources, and found none: the Molor-Erdene detention is the closest documented case nearby, its current status is not established, and no dismissal of it has been shown. The case now sits inside the ministry of a man who built his public name on one principled resignation.
Under Decode Mongolia's reply law, the minister received the claims in writing before publication, with ten working days to answer. The questions put to him:
The signed IAAC declarations, rather than summaries, would settle the Yarlag percentage and what the ₮0 entries — including the Harte Gold line — actually are. Current registry extracts for the five companies would settle the ownership map as registered, not as declared. Contract-register and Glass Account payment lines would change the money story in either direction: a state contract for any of his companies would open it; a confirmed absence would close that line. The dismissal instrument, the Prime Minister's 17 September 2026 letter to the President, and the purge orders would settle who held the firing pen in September. The Court Decision Execution Agency file would show whether the purge happened. The Molor-Erdene case file would establish whether the speech case survives under the new minister. The draft registration bill and the ministry's list behind the 2,173 unfinished apartments, checked against Euroconstruction's project list, would answer the central question. Erdenes Mongol and Oyu Tolgoi board records for 2009–2015 would close the state-mining years with primary paper.
