Given the following context:  The sessions were interrupted by the escalating disagreement between Waters and Pink Floyd over who had the rights to the Pink Floyd name. O'Rourke, believing that his contract with Waters had been terminated illegally, sued Waters for £25,000 of back-commission. In a late-1986 board meeting of Pink Floyd Music Ltd (Pink Floyd's clearing house for all financial transactions since 1973), Waters learnt that a bank account had been opened to deal exclusively with all monies related to "the new Pink Floyd project". He immediately applied to the High Court to prevent the Pink Floyd name from being used again, but his lawyers discovered that the partnership had never been formally confirmed. Waters returned to the High Court in an attempt to gain a veto over further use of the band's name. Gilmour's team responded by issuing a press release affirming that Pink Floyd would continue to exist; however, Gilmour told a Sunday Times reporter: "Roger is a dog in the manger and I'm going to fight him, no one else has claimed Pink Floyd was entirely them. Anybody who does is extremely arrogant."Waters twice visited Astoria, and with his wife had a meeting in August 1986 with Ezrin; Ezrin later suggested that he was being "checked out". As Waters was still a shareholder and director of Pink Floyd Music, he was able to block any decisions made by his former bandmates. Recording moved to Mayfair Studios in February 1987, and from February to March – under the terms of an agreement with Ezrin to record close to his home – to A&M Studios in Los Angeles: "It was fantastic because ... the lawyers couldn't call in the middle of recording unless they were calling in the middle of the night." The bitterness of the row between Waters and Pink Floyd was covered in a November 1987 issue of Rolling Stone, which became the magazine's best-selling issue of that year. The legal disputes were resolved out-of-court by the end of 1987.  answer the following question:  What was the name of the person who applied to the High Court?
The answer to this question is:
Waters
