William Felix Browder is an American-born British financier and political activist. He is the CEO and co-founder of Hermitage Capital Management, the investment advisor to the Hermitage Fund, which at one time was the largest foreign portfolio investor in Russia. The Hermitage Fund was founded in partnership with Republic National Bank, with $25 million in seed capital. The fund, and associated accounts, eventually grew to $4.5 billion of assets under management. In 1997, the Hermitage Fund was the best-performing fund in the world, up 238%. The primary investment strategy of Browder was shareholder rights activism. Browder took on large Russian companies such as Gazprom, Surgutneftegaz, Unified Energy Systems, and Sidanco. In retaliation, on November 13, 2005, Browder was refused entry to Russia, deported to the UK, and declared a threat to Russian national security.

The Dima Yakovlev Law, Dima Yakovlev Bill, Dima Yakovlev Act, anti-Magnitsky law, or Law of Scoundrels is a law in Russia that defines sanctions against U.S. citizens involved in "violations of the human rights and freedoms of Russian citizens". It creates a list of citizens who are banned from entering Russia, and also allows the government to freeze their assets and investments. The law suspends the activity of politically active non-profit organisations which receive money from American citizens or organisations. It also bans citizens of the United States from adopting children from Russia. The law was signed by Russian President Vladimir Putin on 28 December 2012 and took effect on 1 January 2013. The law is informally named after a Russian orphan adopted by a family from Purcellville, Virginia, who died of heat stroke after being left in a parked car for nine hours. The law is described as a response to the Magnitsky Act in the United States, which places sanctions on Russian officials who were involved in a tax scandal exposed by Russian lawyer Sergei Magnitsky against Russian officials; Magnitsky was later found to have been handcuffed and tortured while in jail.

The Magnitsky Act – Behind the Scenes is a 2016 documentary directed by Andrei Nekrasov, concerning the 2009 death in a Moscow prison cell, after 11 months in police custody, of 37-year-old Russian tax accountant Sergei Magnitsky. In 2007, Magnitsky was hired by American-born British financier Bill Browder to investigate the government's seizure of three of Browder's Russian subsidiaries. Discovering evidence of embezzlement, Magnitsky implicated two senior police officers in a tax rebate scam that used shell corporations plundered from Browder's holdings to defraud the Russian treasury of $230 million. Subordinates of those officials then arrested Magnitsky and charged him with the very crime he had exposed.

Magnitsky legislation refers to laws providing for governmental sanctions against foreign individuals who have committed human rights abuses or been involved in significant corruption. They originated with the United States which passed the first Magnitsky legislation in 2012, following the death of Sergei Magnitsky in Russia in 2009. Since then, a number of countries have passed similar legislation such as Canada, the United Kingdom and the European Union.

Sergei Leonidovich Magnitsky was a Ukrainian-born Russian tax advisor. His arrest in 2008 and subsequent death after eleven months in police custody generated international media attention and triggered both official and unofficial inquiries into allegations of fraud, theft and human rights violations in Russia.
