After graduating, Aryal became a Supreme Court advocate, allowing him to argue in Nepal's highest court. His early work included risky cases during the Maoist insurgency (1996–2006), when rebels fought the government, and many people disappeared. Aryal filed habeas corpus petitions, court orders ensuring lawful detention. He also challenged state benefits for former rulers in areas like Bajhang and Mustang. Though the court rejected these, his bold approach stood out. During Popular Movement-II in 2006, he worked at the National Human Rights Commission (NHRC), monitoring rights abuses and witnessing government brutality, including by official Lokman Singh Karki.[1]
Aryal is known for landmark cases. One major case was against Lokman Singh Karki's 2013 appointment to the Commission for the Investigation of Abuse of Authority (CIAA), which fights corruption. Aryal argued Karki lacked moral integrity, citing past reports. After years, the Supreme Court suspended Karki in 2016, leading to his impeachment.[6] Another case was the Giribandhu Tea Estate land dispute, where Aryal sought contempt action in 2025 for non-compliance with court orders. He also opposed a Chief Justice-led government in 2013.
Aryal was appointed as the Minister for Home Affairs and Minister for Law, Justice and Parliamentary Affairs in the interim government led by Prime Minister Sushila Karki on 15 September 2025.[7][8] His selection followed widespread youth-led protests that led to the fall of the previous government. Reports described him as a non-partisan figure with a record of integrity and public interest litigation, particularly his legal challenges against corruption and abuse of authority.[9]
As Minister for Home Affairs (and Law, Justice & Parliamentary Affairs) from 15 September 2025, Aryal made several key decisions early in his tenure:
- He ordered the withdrawal of police personnel and security escorts assigned beyond legal limits to politicians, former officials, and bureaucrats, stating that security resources must not be misused for personal or political benefit.[10]
- He initiated investigations into the deaths of protesters during the 2025 “Gen Z” movement, calling for accountability within law enforcement agencies.[11]
- He emphasized police modernization and reforms, prioritizing transparency, professionalism, and respect for human rights within security agencies.[12]
