If someone were charged with, let's say, three indictable offences and one summary conviction offence, the police force taking the fingerprints would add the summary conviction offence, and you would therefore then have a record of it; however, if it were solely a summary conviction offence relating to a group of offences or a person, you wouldn't take them.
As a matter of fact, would I be correct in saying that if a police force were to send you a fingerprint form and on that fingerprint form were only one or more summary conviction charges, you would not enter it into the data but would return it as is.
