A speeding driver with 25 points on his licence killed a "wonderful" dad who was with his family for a birthday day out.
Ivan Girga, 27, was travelling at 72mph in a 30mph zone prior to the horrific crash in Crumpsall, Manchester.
He ploughed his black VW Golf into a Vauxhall Zafira carrying six members of the same family - including 42-year-old Ghusanfar Illyas, who was killed in the crash.
Mr Illyas' father was performing a 'perfectly legal' U-turn to take his family to the cinema to celebrate his sons' 13th birthday and Eid.
Girga, who had been aggressively overtaking cars before the crash, has now been jailed for nine years.
Manchester Crown Court heard Girga, a mechanic from Bolton, had 25 points on his licence at the time of the incident, which happened at 6pm on June 5.
He should have been banned from driving under the 'totting up' scheme, following convictions for driving with no licence or insurance, reports the Manchester Evening News.
Girga's case was held under the 'single justice procedure', when cases are dealt in private on paper by a single magistrate with a trained legal adviser present.
Prosecutors said that 'due to a combination of weaknesses in process and errors made at the court, Girga was not disqualified from driving despite accumulating a high number of penalty points'.
"Immediate action has been taken to address these failings," prosecutor Andrew Macintosh said, in a statement submitted by the magistrates' court.
"We are issuing updated guidance to staff on the current process for obtaining driver records from the DVLA."
In a court hearing held in July after the crash, Girga accepted he should have been banned previously and was disqualified for 12 months.
A sentencing hearing on Thursday heard that Girga had been at KFC in Harpurhey with his three-year-old son prior to the crash.
On leaving the restaurant, Girga did not wear a seat belt, and did not put a seat belt on his son. The boy got in the front seat and was seen to be stood in the foot well of the car.
He did not have a car seat.
Electrical engineers were working in the road, and one engineer had to jump out of the way as Girga went onto the wrong side of the road to overtake other cars which had stopped for the workers, who were wearing hi-vis jackets.
Another witness who saw Girga's car prior to the crash presciently said 'this car is going to crash with someone'.
Girga then overtook a line of cars which had stopped for a pedestrian crossing.
Meanwhile, Mr Illyas and his family were in the silver Vauxhall Zafira, which his father was driving to give them a lift into Manchester.
After they came off the curb outside their home, and moved onto the road to perform the U-turn, Girga ploughed into the side of the Zafira.
Police experts found he was travelling at 53mph immediately prior to the collision.
Following impact, Girga lifted his son out of the car, and then got out himself. He asked the driver of a car which had stopped to take him and his son to hospital.
The driver agreed, and they travelled to the A&E department at North Manchester General Hospital.
At the hospital, Girga told a nurse that his son had been injured after falling from a bicycle. The boy had sustained a broken arm during the crash.
Shortly after the boy's mother appeared at the hospital. She had a 'heated argument' at the hospital, and Girga left.
He returned shortly after, and the police had arrived by then. He lied by telling officers that he was the passenger in the Golf.
Girga lied again in interview the following day after he had been arrested, claiming another man had been driving at the time.
Ambulances arrived on Crescent Road at 6.25pm and found Mr Illyas having trouble breathing.
He was suffering bleeding into the chest cavity, and his condition worsened at hospital. He went into cardiac arrest while awaiting surgery, and was pronounced dead at 11.10pm.
Mr Illyas' wife, also 42, suffered a broken neck.
His son, 13, suffered a broken jaw, chest injuries, bruising to his lungs, multiple rib fractures, a fractured collarbone, abdominal injuries, bruising to the kidney and multiple pelvis fractures. He also became deaf in one ear following the crash.
The boy was discharged a week later, only to be told his father had died.
Mr Illyas' 15-year-old daughter suffered a fractured pelvis, while his 79-year-old father who was driving the car sustained a broken ankle.
Mr Illyas' sister, 32, did not suffer any broken bones but was diagnosed with compartment syndrome, and her husband, 31, suffered pain to his arm.
In a statement read to the court, Mr Illyas' wife, Ghazala Shaneen, said: "I find it difficult to put into words the impact this tragedy has had upon me.
"Ghusanfar was a really good, kind, helpful and wonderful man. He was everything a husband should be. Without doubt he was my everything."
Speaking of when a doctor told her that her husband had died, she said: "I didn't believe her. I told her to go and check because it could not be true."
She added: "The day of the crash was meant to be a celebration. We were so happy and in an instant everything changed.
"I hope the driver of the other car knows how his actions have devastated our lives so much."
Miriam Anees, Mr Illyas' sister who was injured in the crash, said she had suggested the family get the tram into Manchester, but her brother said they should use the car as he wanted to spend more time with his family.
"I just wish he had gone on the tram, he would still be here if he wasn't in the car," she said in a statement.
Mr Illyas' mother said she was in utter shock.
"It was like a bomb going off in my mind. I felt I was going to lose my entire family."
At the time of the crash in June, Girga had 25 points on his licence.
Usually drivers face a minimum of a six month driving ban if they incur 12 points of more within a three year period.
The court heard that 'a combination of weaknesses in process and errors made at the court' meant that Girga was not banned.
But being disqualified from driving has not stopped Girga from getting behind the wheel previously.
The court heard that Girga has 20 previous convictions, for 36 offences, including for offences of dishonesty and breaches of court orders.
Girga also has a number of previous convictions for driving offences.
Girga, of Wigan Road in Bolton, pleaded guilty to one count of causing death by dangerous driving; and four counts of causing serious injury by dangerous driving.
He denied a further three counts of causing serious injury by dangerous driving, as his lawyers claimed the injuries sustained were not serious within the meaning of the law.
Those counts were ordered to lie on file, after prosecutors said it would not be in the public interest to pursue them given his guilty pleas to the other offences.
Defending, Waheed Baber said that Girga is 'unable to sleep' and has 'flashbacks' of the incident, saying that he is remorseful for his actions.
He said that Girga, who worked as a mechanic, will not return to his job and does not want to drive a vehicle again.
Sentencing, Judge Patrick Field QC said Girga showed 'complete disregard for the safety of others', and that he 'deliberately ignored the rules of the road'.
Girga was also banned from driving for 12 years and three months.
