Leeds property firm appeals £20,000 court fine for flytipping.
But she warned them not to allow feelings of “sympathy or anger” to enter into their deliberations.
Preston Crown Court Judge Heather Lloyd said the “terrible” night in which university student Matthew Hesketh lost his life was a tragedy for all concerned.
The defendant, Adam Catterall, she said, was “by all accounts a decent, hardworking young man”.
However, she stressed to the jury that any feelings of sympathy or anger must be set aside and they should reach their verdict on the evidence they had heard over the last three days.
Catterall, 19, of Mill Lane, Goosnargh, denies a charge of causing death by dangerous driving in February last year.
The trial has heard that his Peugeot 106 crashed side on with a taxi travelling in the opposite direction on Preston Road, Longridge late at night as the driver, together with two of his friends, was looking to buy food. One of his friends was badly injured but Matthew, 18, of Woodplumpton Lane, Woodplumpton, a back seat passenger, died at the scene.
He was a University of Central Lancashire student and worked part time with the defendant in a restaurant.
The taxi driver was also badly hurt in the crash on a gentle right hand bend, the trial heard.
A Leeds landlord appealed against a court ruling after being faced with a five figure fine for flytipping and illegally disposing of waste.
Leeds City Council officers found eight bags of waste on Chapeltown Road that belonged to Moorland Property Services Ltd.
Further investigation into the company revealed the firm did not have the necessary practices in place to ensure their waste was disposed of correctly.
The company was issued with two £300 fixed penalty notices following a court hearing in April 2015.
But despite reminders they failed to pay and were later prosecuted under the Environmental Protection Act 1990 for failing in their duty of care.
The landlord and letting agent, Mohammed Zaheer, was fined £20,000 and ordered to pay £1,865 court costs as well as a £120 victim surcharge.
The company claimed to have disposed of the rubbish in a skip but failed to produce evidence that supported the claim.
The firm also failed to provide evidence that the person responsible for transporting the waste was authorised to do so and that waste was disposed of legally.
Instead, the company had been illegally disposing of its commercial waste at the council's recycling centres, which are for residents' household waste only.
Following the case Mohammed Zaheer applied to have the matter reopened and was initially refused.
However, Mr Zaheer then appealed against this refusal and following further discussions with Leeds City Council in September 2015 agreed to pay a sum of £3,654.53 made up of two fixed penalties of £300, the original costs of £1,865, extra investigation costs of £420 and legal costs of £769.53.
Mr Zaheer also agreed to meet with officers from Leeds City Council's environmental team to discuss the future business operations of Moorland Property Services Ltd. No further action was taken against the defendant.
