[6] A month later, he was ridden by Frankie Dettori when he started 2/9 for a graduation race (for horses with no more than one previous win) at Windsor Racecourse and won by six lengths from Silly Habit.
[7] Cochrane regained the ride when Legal Case was moved up in class for the Listed Winter Hill Stakes at Windsor in August, in which he was matched against older horses for the first time.
Starting at odds of 18/1 he was towards the rear of the nineteen-runner field for most of the way before making steady progress in the straight and finishing eighth, less than five lengths behind the winner Carroll House.
Less than two weeks after his run at Longchamp, Legal Case, ridden by Cochrane, was one of eleven horses to contest the Champion Stakes over ten furlongs at Newmarket Racecourse.
Dolpour was made favourite on 4/1 with Legal Case 5/1 second choice in the betting alongside the four-year-old Ile de Chypre, the winner of the Juddmonte International.
[10] Legal Case remained in training as a four-year-old, but did not appear until the Royal Ascot meeting in June, when he finished fourth behind Batshoof, Relief Pitcher and Terimon in the Prince of Wales's Stakes.
Eighteen days later he started at odds of 14/1 for the King George VI and Queen Elizabeth Stakes at Ascot but made no impact and came home tenth of the eleven runners.
The best of his offspring included Evil Knievel, a Grade I winner in Brazil and Virginie, who won the Beverly Hills Handicap at Hollywood Park Racetrack in 1999.
