Robinson had instructed his lawyer "to read out a series of past Contempt of Court findings against newspapers which (in summary) had not led to jail terms for editors or reporters accused of disrupting trials", according to BBC reporter Dominic Casciani, but to no avail, with judges imposing a custodial term only one month shorter than his previous sentence, declaring that "the main goal of the penalty is punishment and deterrence". Some pelted police with bottles and cans and officers donned their helmets.
Robinson streamed the defendants, charged with the sexual exploitation of minors in 2017, on Facebook during their trial, while court rules prohibited the release of the case details at that time.
In a written ruling, Dame Victoria said Robinson had claimed his intention in making the broadcast was to "denounce the media" for their behaviour.
The judge said the words he used in the video would have been understood by viewers as "an incitement" to harass the defendants and "gave rise to a real risk the course of justice would be seriously impeded".
Robinson, 36, was originally sentenced to 13 months in jail but was released two months later after an appeal.
The case was then referred back to the Attorney General, who announced that it was in the public interest to bring fresh proceedings.
The far-right political activist was found to have illegally filmed defendants in a criminal trial and uploading the broadcast to Facebook.
Robinson's barrister Richard Furlong raised the possibility of an appeal against the court's decision and was told he has 28 days to apply.
Aidan Eardley, representing the Attorney General, told the court about previous punishments handed out in cases of contempt.
Anyone found in contempt of court can be jailed for up to two years, receive an unlimited fine, or both.
Contempt of court laws exist to ensure people get fair trials.
Anyone can be found in contempt if they are deemed to have created a "substantial risk" of prejudice against a suspect, with juries not allowed to be influenced by anything other than the evidence heard in court.
If someone interferes with a trial, the defendants can walk free and a new trial may have to be held.
He was given a six-month prison sentence for the Leeds offence and a further three months for an earlier contempt. Proceedings become "active" when a suspect is arrested.
