The first company convicted for corporate manslaughter will have to pay a £385,000 fine after it lost its appeal.
Cotswold Geotechnical Holdings became the first firm convicted under new corporate manslaughter legislation at Winchester Crown Court in February, following the death of employee Alexander Wright in September 2008.
The Lord Chief Justice said it was "unavoidable and inevitable" that the company would probably have to go into liquidation to pay the fine.
Members of the prosecution team Mark Ellison QC and Adrian Darbishire said in a statement: “As far as sentence was concerned, the fine imposed was appropriate. To limit a fine to the level which this company was capable of paying would have resulted in a ludicrous penalty.
“The trial judge correctly applied the Sentencing Guidelines, had regard to the need to consider the means of the company, but also had regard to the recognition in the guidelines that, in some cases, putting the company out of business may be inevitable, as it was in this case.”
Peter Eaton, the company's managing director, had also been charged with manslaughter by gross negligence and a health and safety offence. However, these personal charges were dropped because of his poor health.
