While Home Office lawyers had attempted to block "The Big Bang" rapper from entering the country, Justice Nicholas Stadlen supported a fellow High Court judge's ruling by continuing an injunction on Rhymes' expulsion from Britain, the BBC reported Saturday.
This week's legal ruling allowed Rhymes, whose real name is Trevor Smith Jr., to perform at a charity event at London's Royal Albert Hall.
Stadlen had said during his ruling that Smith should be allowed to enter Britain in part because of the thousands of volunteers eagerly awaiting his performance at the Orange RockCorps show.
"What weighs in the balance is not just what effect that would have on Mr. Smith, to which I pay considerably less regard than the effect on the 4,000 volunteers who would be disappointed if he didn't perform this evening," the justice said.
The BBC said Smith, 36, had been detained at London City Airport for 12 hours Thursday prior to the court's ruling.
