Gary Perry said there did not seem to be enough of a deterrent in the fines the court was imposing.
‘If this trend continues people will have to start going to prison,’ he said.
Three defendants in court were fined at least £900 and taken off the roads for two-and-a-half years or more. All three had pleaded guilty after giving breath samples revealing more than 80mcg of alcohol in 100ml of breath. The legal limit is 35.
Lisa Elsworth, 62, of St Jacques, St Peter Port, was stopped after driving down Le Val des Terres on the night of Liberation Day.
She was executing a three-point turn very slowly and had collided with a parked car. A breath test revealed 84mcg of alcohol in 100ml of breath.
Advocate Sarah Morgan said her client had been drinking earlier in the day and mistakenly thought she had recovered sufficiently to be able to recover her car.
A £900 fine and a two-and-a-half year driving ban were imposed.
Claire Austin, 58, of Paris Street, St Peter Port, was found asleep in her car in Salerie car park on 10 May after driving along Salerie Corner.
Members of the public had alerted police to Austin after becoming concerned for her wellbeing.
Her breath test read 83mcg.
Advocate Samuel Steel, defending, said Austin had suffered a lapse in judgment and, as an occupational nurse, understood the damage that drink-driving could do.
Judge Perry said the case was an ‘all-too familiar story’ of an incident occurring after an individual had taken their vehicle into town, intending not to use it to go home, or not to drink.
‘The court has to treat such incidents seriously,’ he said.
A £900 fine and a two-and-a-half year driving ban were imposed.
Aigars Melnalksnis, 51, of La Rue des Croisee, Forest, was found by police in the upper garden area of Petit Bot with a bottle of spirits after driving down from the Manor Hotel at about 6.30pm on 4 May. He provided a breath sample of 92mcg.
Judge Perry said he was surprised Melnalksis was functioning as a human being based on his reading, never mind driving a vehicle.
The court imposed a £1,000 fine and a three-year driving ban.
Josyline Gitonga, 30, of Victoria Road, St Peter Port, was fined £900 and banned from driving for three years after she failed to provide an appropriate breath sample when requested after being stopped while driving along Fountain Street on 6 May.
A non-evidential roadside breath test had returned a reading of 89mcg.
As the holder of a provisional licence, she also admitted driving without L plates and without a co-driver. She was fined £500 with a six-month concurrent driving ban.
She denied driving without insurance and that case was adjourned.
Another woman also appeared and denied a drink-drive charge dating back to March. The case against her was adjourned.
