In 2010, HOGL sold its 50 percent stake in Ugandan oil fields to Tullow Uganda for US$1.5 billion. The Uganda Revenue Authority (URA) applied a US$404 million capital gains tax on the transaction and HOGL refused to pay. A four-year battle in various courts ensued. Ugandan officials, including President Yoweri Museveni and the then-URA Commissioner-General Allen Kagina demanded the payment from Tullow, threatening not to renew its exploration licenses, which were about to expire, unless it deducted the tax from its payment to Heritage and remitted it to the URA. Eventually Tullow made a down payment and deposited the rest in escrow, pending legal resolution of its appeal, which came in 2013. Tullow also successfully sued HOGL to recover taxes they had paid on its behalf.

This is the global professionalization of leaktivism. The days of WikiLeaks amateurism are over."
