It was quite a big case, as you can see from the number of prosecution witnesses called:
"£31,000 TAX ALLEGATIONS.
71 WITNESSES TO BE CALLED FOR PROSECUTION.
It was intimated at Edinburgh Sheriff Court to-day, when William Lawrie, director and secretary, and John Archibald Clark, head brewer in the employment Edinburgh United Breweries. Ltd.. Edinburgh, appeared, that their trial on a charge defrauding the Commissioners' Customs and Excise of sums amounting to £31,291 would take place in the High Court on March 5th.
There are 71 witnesses for the prosecution. "
Nottingham Evening Post - Saturday 23 February 1935, page 4.
And it lasted more than a week, before the inevitable guilty verdicts. There's a little more detail given as to exactly how the fraud was perpetrated:
"BEER DUTY EVASION,
TWO SCOTTISH BREWERY
After a trial bating eight days William Lawrie, managing director and secretary of Edinburgh United Breweries, and John Archibald Clark, head brewer, were at Edinburgh yesterday found guilty of conspiring to defraud the Customs and Excise authorities.
Lawrie was sentenced to 21 months' imprisonment and Clark to 12 months' imprisonment.
An appeal on behalf of Lawrie was lodged and he was liberated on bail.
The charge alleged that the company had evaded the payment of beer duty amounting to £2,291. It was stated that the methods adopted were the abstraction of worts before the Excise officers had taken measurements and the running of secret brews upon which no duty was paid.
The Lord Justice Clerk said that having regard to the magnitude of the sum involved and the period over which the fraud was carried on he had difficulty in refraining from passing sentence of penal servitude.
On the other hand the accused were both men who had good records. Grave as the frauds were, the money did not go directly into their pockets although they might have derived indirect benefit."

The managing director, unlike the head brewer, refused to accept the guilty verdict and apealed. Unsurprisingly, without luck:
"BREWERY DIRECTOR'S APPEAL DISMISSED
The Scottish Court Criminal Appeal at Edinburgh yesterday, dismissed the appeal Wm. Lawrie, director and secretary of the Edinburgh United Breweries, Ltd., against his conviction sentence of 21 months imprisonment on a charge of being concerned with other employes of the company in a fraud the Inland Revenue whereby the company avoided payment beer duty amounting to £31,291. Lawrie had been tried along with John Archibald Clark, head brewer of the company, who was sentenced to 12 months imprisonment."

I wonder what happened to Lawrie and Clark when they were released? Did they ever work in the industry again? I'd love to find out.
