Nurses at Rampton Hospital were convicted of ill-treating patients based solely on uncorroborated evidence from mentally disordered patients with criminal backgrounds. The case addressed whether judges must give the standard 'dangerous to convict' warning for such witnesses outside established categories, and whether jury irregularities rendered verdicts unsafe.
Facts
The appellants were nursing staff at Rampton Hospital, a secure institution for mentally disordered patients, many of whom had been convicted of serious crimes. Following a television programme alleging ill-treatment, police investigations led to multiple trials. The prosecution case depended largely on uncorroborated evidence from single patients who had criminal records and mental disorders.
In the Spencer appeal, an additional issue arose concerning a juror (Mr. Peet) who displayed bias against the defence throughout trial. After discovery that his wife worked at a related hospital, he was discharged but permitted to drive three jurors home. Despite the judge’s warning not to discuss the case, they did so during the half-hour journey.
Issues
The Corroboration Warning
Whether, when prosecution evidence comes solely from a witness outside the established categories (accomplices, sexual complainants, children) but with analogous characteristics of unreliability, the judge must warn the jury it is ‘dangerous to convict’ without corroboration.
Jury Irregularities
Whether the incidents involving the biased juror rendered the Spencer convictions unsafe and unsatisfactory.
Judgment
The House of Lords dismissed the Smails appeal but allowed the Spencer appeal on grounds of jury irregularities.
On the Corroboration Warning
Lord Ackner, delivering the main judgment, held that while a warning was required for witnesses with analogous characteristics to established categories, no magic formula was necessary:
“It has been said both in the Court of Appeal and in your Lordships’ House, that the obligation to warn a jury does not involve some legalistic ritual to be automatically recited by the judge, or that some particular form of words or incantation has to be used and, if not used, the summing up is faulty and the conviction must be quashed.”
Judge Hopkin’s warning was found adequate. He had told the jury:
“You must, ladies and gentlemen, approach the evidence of [the patients] with great caution. Why? Well for three reasons, Firstly, because they are all persons of bad character… Secondly… they were all persons suffering from some form of mental disorder… Thirdly, they may of course have all conspired together to make false allegations.”
On Jury Irregularities
The Lord Chancellor found the Spencer convictions unsafe, noting:
“This was a case of total want of corroboration, a majority verdict of 10-1, and a wholly unauthorised and improper conversation between a juror who had been sent off the jury as not suited to remain there with three of the remaining jurors in the absence of the other eight and in disregard of an express warning by the judge against such conduct.”
Lord Ackner expressed a “lurking doubt, that justice may not have been done, which makes me conclude that the verdict was unsafe.”
Implications
The case confirmed that mental patients are not a separate category requiring the standard corroboration warning, but where witnesses possess analogous characteristics of unreliability, an emphatic warning tailored to the circumstances is required. The judgment emphasised flexibility in judicial directions while maintaining protection for accused persons facing inherently unreliable witnesses. It also reinforced the strict standards for jury conduct and the courts’ willingness to quash convictions where irregularities cast doubt on verdict safety.
Verdict: The appeals of Spencer, Ball and Mason were allowed and their convictions quashed due to jury irregularities. The appeals of Smails, Ball and White were dismissed and their convictions affirmed.
