The UN-backed Special Court for Sierra Leone (SCSL) on Sept. 26 rejected an appeal by former Liberian president Charles Taylor of his convictions for war crimes committed during the decade-long civil war in Sierra Leone. According to a press release from the court, Taylor's lawyers appealed his convictions on 42 grounds, arguing that the Trial Chamber erred in evaluating evidence and that the 50-year sentence was "manifestly unreasonable." The court ruled that his guilt had been proved beyond doubt and upheld Taylor's 50-year sentence. The sentence came after Trial Chamber II convicted (PDF) Taylor of planning as well as aiding and abetting crimes committed by rebel forces in exchange for diamonds during the civil war, including acts of terrorism, murder, rape, sexual slavery, conscripting or enlisting children into armed forces, enslavement and pillage.

The Joint Task Force at Guantánamo Bay said Sept. 23 that they would no longer issue daily updates on detainee hunger strikes. This announcement sought to effectively declared the end of the unprecedentedly broad, six-month long, prisoner protest. There are now 164 prisoners in Guantanamo, and as many as 106 were on strike at the peak of the protest in July. Only 19 detainees are still classified as on hunger strike. For those 19 prisoners, force-feeding continues. The hunger strike has brought attention to the prison, and caused US President Barack Obama to renew his pledge to close the facility.

An Egyptian court on Sept. 23 banned the Muslim Brotherhood and ordered its assets confiscated as part of the military government's crackdown on the group. The Cairo administrative court declared that its ruling would apply to all organizations affiliated with the Muslim Brotherhood, including its political arm, the Freedom and Justice Party. Although the Muslim Brotherhood was banned for most of its 85-year existence, it attained power when Islamist Mohamed Morsi became president in 2012. It is unclear if the Muslim Brotherhood will appeal the ruling.

On Sept. 20, Amnesty International (AI) called upon members of the UN to demand Sudanese President Omar al-Bashir turn himself in to the International Criminal Court (ICC), where he faces charges for war crimes, crimes against humanity and genocide allegedly committed during the Darfur conflict. Al-Bashir has continually ignored the charges against him and is still being protected by the Sudanese government. AI is calling for the international community to come together in cooperation with the ICC in order to bring al-Bashir to justice. Despite the warrants for his arrest, al-Bashir has reportedly applied for a US visa in order to attend the 68th session of the UN General Assembly in New York.

Iranian lawyer and prominent human rights activist Nasrin Sotoudeh was permanently released on Sept. 18, after spending over two years in prison. Sotoudeh was serving six-year sentence for her September 2010 arrest and conviction for "propaganda against the system" and "harming national security." Other prisoners serving prison terms related to the 2009 mass protests were also released that day. Among the released prisoners was former Iranian deputy foreign minister Mohsen Aminzadeh who was sentenced to six years in prison for his participation in protesting the 2009 presidential election. It is estimated that the total number of prisoners released is around 10.

A judge for the US District Court for the Southern District of New York ruled (PDF) Sept. 13 that the US government does not have to release photographs and videotapes taken during the investigation of Mohammed al-Qahtani's connection to the September 11 attacks. Al-Qahtani was held in Guantánamo Bay until his charges were eventually dropped. The videotapes depict al-Qahtani's interrogations, something the Center for Constitutional Rights (CCR) claims should be public record. However, Judge Naomi Reice Buchwald stated:

The nonprofit human rights law firm Justice Project Pakistan (JPP) released a report  on Sept. 5 detailing the conditions at Bagram Prison in Afghanistan, a facility that continues to detain non-Afghan prisoners of the US despite not being under US control since March. According to the JPP, many of these detainees are being held indefinitely without charges, trial or access to a lawyer. Many prisoners have testified to being captured and held in the prison without ever being told about the basis for their detainment.

UN Secretary-General Ban Ki-moon on Sept. 3 questioned the legality of the US plan to strike Syria. Ban stated  that the use of force is lawful only in two very limited circumstances: (1) when used in self-defense according to Article 51 of the UN charter or (2) when the UN Security Council (UNSC) approves such action. Ban questioned whether the planned use of force would solve the situation in Syria, adding that such use would cause more damage. Ban noted that UN inspectors are deployed to investigate whether chemical weapons have been used in Syria. According to Ban, the UNSC would be able to overcome its differences and take action once investigations are done. A potential US strike has been opposed by Russia. President Vladimir Putin on on Sept. 4 warned the US and its allies to take any unilateral action. However, he stated that he may support the UN action once investigations confirm use of chemical weapons.
