Alas if it were only that simple, pauln90!
Whilst the maximum penalty for this offence is six months imprisonment and a lifetime ban, magistrates� sentencing guidelines show a starting point of a 12 month disqualification and a community sentence, so the only real mystery is why only a fine (and a small one at that) was imposed and not a community penalty.
The idea of magistrates being provided with evidence of the first reading is laudable, but not on. Such evidence is inadmissible to support the offence of failing to provide a specimen and if it were heard �in error� it would have to be disregarded. It is similar to the offence of failing to provide driver�s details in speed camera cases. That offence cannot be supported by evidence of the alleged speed recorded.
Magistrates have to provide reasons for all of their decisions, especially when they depart from their guidelines. The prosecution could have made more of any evidence which might have demonstrated the defendant�s ability to drive (but could not use the single breath reading). It seems possible that they did not do so.
Don�t always blame their Worships. Very often to provide a good headline, newspapers and TV producers sometimes �forget� to mention salient facts which the magistrates have taken into account.
