After the 12 June 2009 presidential election, Supreme Leader Ali Khamenei publicly backed Mahmoud Ahmadinejad’s official victory and authorised a security crackdown on Green Movement protests.
Context
Ahmadinejad was declared winner. Mousavi and Karroubi contested. The IRGC and Basij beat and detained. Neighbouring 2011 house arrest is a later freeze. He did not personally club every demonstrator.
House arrest 2011 is neighbouring. Mahsa 2022 is a different decade.
The Supreme Leader of Iran is commander-in-chief and the highest constitutional authority. He does not write a US presidential strike order, an IAEA Board resolution, or a Hamas military plan. Presidents, the IRGC, and the Guardian Council implement and share specific files.
Why it matters
The path is democratic resilience: a completed Leader-backed post-election crackdown is a dated civic-space collapse.

What the sources establish
Office of the Supreme Leader of Iran carries the official instrument or communique. Reuters records the same dated act independently.
Established: June 2009 Leader backing of the official result and a documented crackdown, independently reported.
Not established: a unique later exile coefficient from that week, or that every later disqualification was this Friday prayer.
Ahmadinejad claimed the vote. The IRGC and Basij implemented.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies Khamenei backs Ahmadinejad’s re-election and the crackdown on Green protests, not a later speech about Khamenei backs Ahmadinejad’s re-election and the crackdown on Green protests.
Co-authors and later implementers named in Context remain on the file. If a later repeal, stay, or successor instrument exists, it needs its own date and its own row. The contribution described on this Person row is limited to He set the political weather and commanded the security organs. Ahmadinejad claimed the vote. The IRGC and Basij implemented. That limit is the alternative to treating office-holding as authorship of every later series.
