Sufficiency and Corroboration Flashcards
What is sufficiency?
Sufficiency relates to whether there is sufficient evidence to prove a certain fact.
What is corroboration?
Corroboration is a species of sufficiency.
The corroboration rule is unique to Scots law. However a Bill which may abolish corroboration may pass in the near future.
Corroboration means that there must be two independent sources of evidence for every crucial fact.
[The types of sources that might be relied on will vary. Most often there will be a witness and another witness or a secondary sort of fact.]
What is the rationale for corroboration?
To make sure that every fact that needs to be established is verified by more than one source.
“No matter how trivial the offence and how high soever the credit and character of the witness, still our law is averse to rely on his single word, in any enquiry which may affect the person, liberty and fame of his neighbour; and rather than run the risk of such an error, a risk which does not hold when there is a concurrence of testimonies, it is willing that the guilty should escape.” (David Hume, Commentaries on the Law of Scotland, Respecting Crimes, 4th edn (1844) vol ii, 383)
Who decides whether there is corroboration?
Whether there is corroboration is a question of law, thus it is a question for the judge and not the jury.
What is the outcome of successful corroboration?
If corroboration is in existence then in theory the court is able to convict the accused (it may be still the case that the prosecution have not proved the case beyond reasonable doubt, but without corroboration it is impossible to convict).
Where there is corroboration, there is a sufficiency of evidence. This means that the court may convict, but it is not required to – it may still conclude that the case has not been proven beyond a reasonable doubt. But if there is no sufficiency, there can be no conviction.
When is corroboration required in civil matters?
Corroboration is no longer required in civil matters: Civil Evidence (Scotland) Act 1988 s 1, although note that certain family actions require evidence from a person who is not one of the (alleged) parties to the marriage or civil partnership: section 8 of the 1988 Act.
When is corroboration required in criminal matters?
Corroboration is required to prove all criminal offences, unless statute provides otherwise.
When does statute provide otherwise?
Walkers on Evidence, 3rd edn para 5.5.1 n 72 lists some examples:
⁃ Game (Scotland) Act 1832 ss 1, 2, 6;
⁃ Poaching Prevention Act 1862 s 3;
⁃ Wildlife and Countryside Act 1981 s 19A;
⁃ Road Traffic Offenders Act 1988 s 21;
⁃ Salmon and Freshwater Fisheries (Consolidation) (Scotland) Act 2003 ss 9, 10, 13, 14, 15, 16, 17, 17A, 17B, 18, 19, 20, 23, 31, 33, 38, 51A – can you see a pattern?
Are the defence required to prove criminal offences with corroborated evidence?
Although the law of evidence may in some circumstances place a burden of proof on the defence in a criminal case, the defence are never required to prove anything by corroborated evidence.
*Gillespie v Macmillan 1957 JC 31
It is not enough to have more than a “single witness”: cf *Gillespie v Macmillan 1957 JC 31 – theoretically authoritative (a Full Bench) but universally condemned: see e.g. W A Wilson, “The logic of corroboration” (1960) 76 SL Rev 101;
Smith v Lees 1997 JC 73 at 103-104 per Lord McCluskey.

What are crucial facts?
Crucial facts must be proven by corroborated evidence. These are the facts which make up the definition of the relevant crime
*Smith v Lees 1997 JC 73 at 79 per Lord Justice-General Rodger
(note that he is concerned with the definition of rape as it stood prior to Lord Advocate’s Reference (No 1 of 2001) 2002 SLT 466:
“…there are certain facts which can be established only by corroborated evidence. These facts are variously described as ‘fundamental’ or ‘crucial’ or ‘essential’ facts or as the facta probanda, the facts which require to be proved. They are the elements which need to be established if the accused is to be found guilty of the crime in question–so, in rape, for instance, the Crown requires to prove (1) penetration of the complainer’s vagina by (2) the accused’s private member, (3) forcibly and (4) without the complainer’s consent. These four fundamental facts require to be established by corroborated evidence.”
Yates v HM Advocate 1977
NB Not all facts in dispute are crucial facts
⁃ The accused was charged with raping a 16 year old girl and threatening her with a knife while doing so. There was no corroboration that he had a knife. The defence tried to argue that this lack of corroboration should have meant that the jury was instructed to remove any reference to the knife in delivering their verdict.
⁃ The High Court held that the use of the knife wasn’t a separate crime - it wasn’t an aggravation to the crime - it was simply the way the crime was carried out. Thus it contributed to the fact that the accused had used force but it wasn’t something which would preclude a jury from coming to the fact that he was guilty. Thus it wasn’t a crucial fact and thus corroboration was not required.
What is the outcome if a crucial fact is not proven by corroborated evidence?
If even one crucial fact is not proven by corroborated evidence, there can be no conviction: see e.g. Lockwood v Walker 1910.
Complications to the general rule
⁃ This sounds very straightforward but sometimes because of the order of proceedings things can get a little complex. For example there are provisions in the Criminal Procedure (S) Act 1995 (ss 97 and 160) which allow the defence to object to a case that has been brought against their client on the basis that there is ‘no case to answer’ - this essentially means that at the end of the prosecution case, if the defence thinks that there is insufficient evidence at this point then they can argue that there is no case to answer. If this is successful then the accused will be acquitted. The reason this is important is that sometimes on appeal it might be decided that actually a plea that there was ‘no case to answer’ which was repelled at first instance should actually have been allowed and in this case given that the trial went ahead there can be the possibility that even though there was an insufficiency of evidence at the start (and thus the accused should have been admitted), when more evidence comes out during the trial the accused may be convicted. But is this right? Should the accused’s conviction be quashed on the basis that they should have been acquitted earlier? This actually happened in the following case:
⁃ *Gonshaw v Bamber 2004
*Gonshaw v Bamber 2004
⁃ The accused was charged with intentionally disrupting a golden eagle while it was building a nest which is a criminal offence. The accused argued that there was insufficient evidence to identify him as the person who was meant to have carried out this offence so there was no case to answer. This objection was objected so the case went ahead. The accused went on to incriminate himself and he was then convicted. But on appeal against the conviction the court reached the conclusion that the Sheriff had been wrong to reject the plea of no case to answer, so the question for the court was, given this error by the sheriff, had there been a miscarriage of justice overall (i.e. since the accused supplied extra evidence for the prosecution after the point at which, in hindsight, the case should have been stopped and he should have been acquitted)?
⁃ The court held that the effect of the sheriff’s mistake was that the accused had been wrongly deprived of an acquittal and so this amounted to a miscarriage of justice and his appeal was allowed.
Criminal Procedure (Scotland) Act 1995 s 107A
NB The prosecutor now has a right to appeal against a no case to answer submission being upheld
Criminal Procedure (Scotland) Act 1995 s 107A, as inserted by the Criminal Justice and Licensing (Scotland) Act 2010 s 74.
Does corroborative evidence have to be directly incriminating?
Corroborative evidence need not be[ It might be the case that it is though.] directly incriminating to be corroborative. Corroborative evidence is “evidence which supports or confirms the direct evidence of a witness”
Fox v HM Advocate 1998
per Lord Justice General Rodger:
⁃ The accused was tried for clandestine injury. The circumstances were that the complainer had been at a party and become drunk and had sex with one man in the bathroom and then later was put to bed by him. She woke up later to another man having sex with her. She told him to stop and he did. At the trial the accused admitted having sex with the complainer but he claimed she had been conscious and consenting until she realised he was a different man than the one she’d had sex with in the bathroom. During the trial the prosecution relied on the complainer’s evidence of her distress to corroborate the case.
⁃ The accused was convicted. On appeal the accused argued that in order to be corroborative evidence the evidence must be more consistent with the complainer’s account of what happened than with any other explanation of her distress. The court held that this was not necessary - it isn’t necessary that this evidence should be more consistent with the complainer’s account than any other account so long as the corroborative evidence was independent and confirmed or supported the complainer’s direct evidence.
⁃ [NB in making this decision the court was overruling the earlier case of Mackie v HM Advocate 1994 in which it was held that corroborative evidence must be more consistent with the direct evidence than any other account.]
Little v HM Advocate 1983 JC 16
“direct evidence” isn’t actually required – a conviction on circumstantial evidence alone is possible
What is identification?
Identification is one of the crucial facts in conviction, so corroboration is necessary.
How can identification be corroborated and what types of problems may arise?
The general position is that if there is an “emphatic positive identification” by one person then very little else is required to corroborate this
Ralston v HM Advocate 1987
⁃ The accused was found guilty of assault with intent to rob. He appealed against the conviction saying that there had been insufficient evidence to identify him as the perpetrator. The evidence which there was against him by way of identification was one positive ID and another witness was able to say during an identification parade that he resembled the attacker and a third person stated that he was probably the attacker. This evidence was deemed sufficient to corroborate, the court held that: when there is an emphatic positive ID little else is required to corroborate.
Mair v HMA 1997
⁃ Accused tried for assault and robbery and the evidence relating to identification was that the police had an identification from three different complainers. On the day after the robbery had taken place the police showed the complainers two sets of photographs in order to try and get them to identify the accused. One of the complainers identified the accused as there attacker but the other two did not do so. But then at the trial the complainer who identified the accused and one of the other complainer’s stated that they had no doubt that the accused was their attacker and they gave descriptions of the attacker which were broadly consistent with those given by the third complainer (so there was a slightly different course of events at the trial).
⁃ The judge told the jury that the third complainer’s description was able to corroborate either of the two complainer’s who had identified the accused at the trial. The accused was convicted.
⁃ The accused appealed on the basis there had been a misdirection. But on appeal, the court held that where there has been positive identification by one witness this can be corroborated by other evidence which is consistent with the identification and the third complainer’s description had been consistent with this, thus the conviction was upheld.
⁃ [The following quote is a description by the third complainer which is extremely vague - it shows how little is required to corroborate an emphatic positive identification.
⁃ “Miss Ferguson did not make a positive identification at the identification parade. She indicated in court that she would not be able to recognise the man. She said he was young, in his mid-20s and had light coloured hair. In cross examination she said that she was not very good at ages and that it was just a guess. She said the man had been taller than she but not much taller, and she was 5 feet 1 or 2 inches. He was just a few inches taller. He did have a large nose. She had not noticed anything unusual about his hands and arms, and she could not recall if she had said that the man had had freckles.”]
What is required to corroborate a confession?
It has been said that “very little” is required to corroborate an “unequivocal confession” (Hartley v HM Advocate 1979 SLT 26), but that is generally now regarded as going too far. A “sufficient independent check” is required to corroborate a confession:
*Meredith v Lees 1992
⁃ The accused was charged with lewd, indecent and libidinous practices towards his niece who was very young at the time - only 14 years old. The accused had confessed to some of these acts and the young niece gave evidence that he had touched her on the leg and he had lain down on her. The sheriff held that when there has been an unequivocal confession little else is required by way of corroboration. The accused appealed against this conviction on the basis that there was insufficient evidence to corroborate his confession.
⁃ On appeal the High Court held that when there has been an unequivocal confession, the corroborative evidence must provide a “sufficient independent check”. In this case the niece’s testimony was deemed to be sufficient to provide a sufficient independent check so the appeal was refused.
