You have been bailed from the police station under Section 47(3) of
the Police and Criminal Evidence Act 1984, as amended by the Criminal
Justice and Public order Act 1994.
This means that the police do not have sufficient evidence to charge
you, but are permitted to release you on unconditional bail while they
make further enquiries to obtain evidence. In this case: the results
of your blood test for alcohol. Once this is obtained then they will
make a decision whether to charge or not.
The Act does not state any time limit. However, the police should make
these further enquiries expeditiously and without delay. If there is
unwarranted delay and a charge is later made, it could be open to a
defence application to the Magistrates Court or Crown Court that there
was an abuse of process.
However, in this case, the time it has taken is still not yet
unreasonable. It would appear that there may be a delay at the
laboratory, or the results have not yet been passed to the
investigating officer. Interestingly, this delay for a drink drive
offence is unusual, so perhaps there is a problem with the sample or
process (I don?t wish to falsely raise your hopes on this). I would
wait until six months and then if nothing has been decided I would
speak to a solicitor with a view of them contacting the police to make
them aware of the possible abuse of process in this case.
Whatever you do, do not fail to report when and where required as they
could re-arrest you. It is not worth the additional problems that this
Section 47/3(b) Police and Criminal Evidence Act 1984 is not available
online, you would have to purchase it from the HMSO or a good book
This answer is from my own knowledge as a former police officer.
I hope this answers your question. If it does not, or the answer is
unclear, then please ask for clarification of this research before
rating the answer. I shall respond to the clarification request as
soon as I receive it.
