Kuzmins, from Latvia, and Vladimirov, from Lithuania, had been celebrating the end of a work project on a wind farm and were planning to fly home via London the following day.
Crown Advocate Carla Carvalho told the Royal Court that the pair had been sitting on the grass area near the Cenotaph when Kuzmins asked a passing stranger to borrow a cigarette lighter.
When Kuzmins then refused to return it, the stranger pulled the lighter out of Kuzmins’s hand and began to walk away. Kuzmins then punched him in the head.
Shortly after, the windscreen of a parked Volkswagen Transporter van was smashed with a whiskey bottle which was later found to bear Kuzmins’s fingerprints.
Kuzmins also mistakenly believed that the stranger whose lighter he had borrowed had stolen his mobile phone, and so he entered the stranger’s block of flats.
Pictured: Dmitrijs Kuzmins (34) and Aleksej Vladimirov (30) were in Jersey for one night on 5 September.
However, Kuzmins and Vladimirov then mistakenly barged into the flat of another couple, thinking it was occupied by the stranger who Kuzmins believed had stolen his phone.
The occupants of the flat – a man and a woman – described being “fuming” and “scared” following the incident.
Crown Advocate Carvalho said: “The woman saw two shadows in the lounge.
“The door flew open and she said: ‘The next thing I knew they were in the room and saying something about a phone.’
“They punched and kicked her partner repeatedly and grabbed her around the throat to choke her.”
She added that the woman no longer feels safe in her own home.
Two neighbours also called the police as the assault took place.
One neighbour told police that she could hear “a man hysterically screaming ‘help’” as well as a woman screaming.
The two men quickly left but were arrested by police officers at 03:15, who found that both were heavily intoxicated.
They pleaded guilty to breaking and entering, assault and malicious damage.
Crown Advocate Carvalho recommended a sentence of three years and eight months for Kuzmins and three years and six months for Vladimirov.
Advocate Allana Binnie, defending Kuzmins, pointed out that the offences took place over ten minutes and the men had been in the couple’s flat for just three minutes.
She said: “If there was ever a case that could be described as ‘a moment of madness’, then this is it.
“It is a moment of madness that has cost the defendants dear.
“They were celebrating the end of a work project and unfortunately they celebrated by drinking too much.”
Advocate Binnie said Kuzmins was “a hard-working family man” and added: “He is remorseful and understands the impact on the victims.”
She added that the sentence recommended by the prosecution was “too high by at least a year.”
Advocate Estelle Burns, defending Vladimirov, said Kuzmins had been “the main aggressor”, punching the man with the cigarette lighter, smashing the windscreen of the van and breaking the door of the flat.
She said: “Mr Vladimirov did not lay a finger on the woman.
“He deeply regrets that he didn’t just walk away, and realises he should have done. There is genuine regret and remorse.”
Advocate Burns said that Vladimirov only failed to plead guilty at his first appearance because an interpreter had not been available, and the admission had still come early enough to avoid the necessity of a trial.
She suggested that a “sentence in the region of two years would be appropriate”.
Lieutenant Bailiff Olsen said that Kuzmins later discovered that no-one has stolen his phone as he still had it, so said: “As well as being serious, the offence was an exercise of total futility.”
He also pointed out that both men had been wearing trainers at the time and said: “Kicking with a shod foot is equivalent to assault with a weapon.
“The defendants are fortunate that they were indicted for common assault, and not grave and criminal assault.”
He told them: “The lives of many people have been affected by this chaotic ten minutes – most of all your own and those of your immediate families.”
Vladimirov was jailed for three years and Kuzmins was jailed for three years and six weeks.
The Jurats sitting were Steven Austin-Vautier and Michael Entwistle.
