As Graham says, innocent until proven guilty. And thank god we live in a society like that.
Your links didn't work, but I found and read the BBC and Independent stories, as well as the Mail's version of events. None of the articles give me good reason to believe Ntege was guilty. In fact, all I can glean from them is that immigration officials decided to make up a story about this bloke, but were so stupid they fucked it up. Maybe they're just racists?
The BBC story says:
'[The judge] said: "I am satisfied that this is a case in which there has been both bad faith and serious misconduct on the part of the prosecution.' [and] '"I am satisfied that officers at the heart of this prosecution have deliberately concealed important evidence and lied on oath."' [and] '"It is a case in which the prosecution should not be allowed to benefit from the serious misbehaviour of the officer in the case or the disclosure officer."'
'The judge said photographs taken at the vicarage and video filmed at the church from June 2011 had not been made available to the defence.'
'The officer in the case and/or the disclosure officer had taken measures to ensure the photographs and video footage were not seen and they had also lied about it on oath, the judge said.'
'Judge Madge also concluded the existence of entries on an investigation log from July 2012 to December 2012 had been concealed and lied about on oath by the officers.'
'...when "immigration officers were questioned in the witness box, it emerged that evidence had been tampered with or concealed, possibly destroyed, video footage had gone missing, and an investigation log had been doctored".'
On this basis, clearly the decision was the correct one. The fact that the judge gave a 'terminatory ruling' rather than pronouncing "not guilty", has no bearing on Ntege's guilt or innocence. There was simply no valid prosecution case.
I wouldn't be surprised if there are people in the UK knowingly presiding over sham marriages, but I am not convinced Ntege is one of them.
BTW, here's (hopefully) the correct link to the new Telegraph story:
