A Spanish sea captain jailed for 30 years for his part in smuggling #100m worth of cocaine into a remote part of Scotland, claimed yesterday that he was the victim of a miscarriage of justice.

The sentence imposed on 31-year-old Jose Boo Torres in February 1994 was one of the heaviest ever handed down by a Scottish court and Torres also argues that the jail term was too harsh.

Lord Weir told Torres that the sentence was intended to act as a signal to others of the folly of bringing ''murderous cargoes of misery and death'' into Scotland.

Torres, currently serving his sentence in Shotts Prison, was the sixth man convicted of being involved in the operation to bring half a tonne of cocaine ashore in a dinghy near Oldany Island, Drumbeg, 40 miles from Ullapool in January 1991.

The drugs were loaded onto a van on the first stage of a journey to London but the van was stopped on the A9 near Newtonmore by an alert off-duty policeman.

The two drugs couriers driving the van were jailed for 10 and seven years and at a later trial at the High Court in Edinburgh three Ullapool men were sentenced to a total of 55 years for their part in the operation.

Torres was caught in 1992 when his ship had to run for shelter to Halifax, Nova Scotia, in rough weather.

A seventh man, who still cannot be named for legal reasons, escaped from police custody in Spain as he was about to be deported to the UK. He is alleged to be the European mastermind behind the plan to smuggle the drugs from Columbia.

Torres was represented yesterday at the Court of Criminal Appeal by Mr Andrew Hardie QC, Dean of the Faculty of Advocates, who said there were six main issues involved in the case.

Was the evidence of a note which the jury found to be in Torres' handwriting and connecting him to one of the Ullapool men, ''Crazy Chris'' Howarth, properly admitted in evidence?

Was the evidence of forensic scientists concerning additional work undertaken by them in the course of the trial properly admitted as evidence?

If the answer to the first two questions was No, was there enough evidence to convict Torres?

Did the trial judge make a mistake in referring in his charge to the jury to events which had taken place outwith their presence?

Was Torres deprived of the right to a fair trial by a failure to present to the jury his position on the handwritten note?

Torres has consistently disputed that he was the author of the note but argues that no proper investigation was undertaken on his behalf and that his defence on this point was not put before the jury.

Torres is also arguing that, even if his appeal against conviction fails, the 30-year-sentence was excessive.

He says that although he was the captain of the Dimar-B which brought cocaine into British territorial waters, there was no proof that he had a financial interest in the vessel which was owned by a company registered in Panama.

According to Torres there was no evidence that he was responsible for organising the importation of the drugs, that he was a major player, or that he had any financial interest in the importation or that he would have derived any significant financial benefit.

He argues that his part in the operation was akin to Ullapool man Noel Hawkins, who landed the cocaine in Scotland and was sentenced to 15 years.

The hearing continues.
