Is the Law on Diminished Responsibility Satisfactory?

Voluntary manslaughter, as established by using the Homicide Act 1957, is determined via 3 sections: dwindled duty, provocation, and suicide p.C.. These are all referred to as partial defences meaning that they do now not give full acquittal of a sentence they best shorten that of homicide to manslaughter. Diminished responsibility is hooked up by way of Section 2 of the Homicide Act which states that “Where a person kills or is birthday celebration to a killing of any other, he shall not be convicted of homicide if he turned into tormented by such abnormality of mind as considerably impaired his intellectual obligation for his acts and omissions in doing or being party to the killing.”


It may be used as a defence to murder if the defendant can prove an abnormality of the thoughts, if, as an instance, the defendant is an alcoholic, or has a intellectual condition as in Byrne (1960), in which the defendant had uncontrollable sexual dreams. The defence is that the defendant does not have the vital manage over their movements, whilst compared to a reasonable individual. Diminished obligation has been criticised for a number of reasons, the very time period ‘Diminished responsibility’ has been criticised with the aid of authorities along with the Butler Committee, who say that it’s miles ‘no longer a clinical truth referring to the accused’. There are also many different regions which makes this area of law debatable as I might be discussing.

Abnormality of mind covers a extensive range of conditions and become describes via Lord Cj Parker in the Court of Appeal in the case of Byrne (1960) as “a country of thoughts so exceptional from that of normal humans that the affordable man would time period it strange.” In Byrne (1960) the defendant who become a sexual psychopath, strangled to dying and then mutilated a younger woman. He become convicted of murder however the Court of Appeal felt that his condition got here in the definition of dwindled duty and so his conviction of homicide become substituted for one of homicide.

The most important problem changed into that the medical examiners had describes Byrnes situation as amounting to ‘partial insanity’ and the Court of Appeal had accredited of this. However, in Seers (1984) it changed into held that comparisons with madness are not useful and ought to be avoided. In this case the defendant stabbed his estranged wife and claimed diminished responsibility on grounds of chronic reactive despair. The trial decide directed that for the defence to be successful Seers needed to be bordering on the insane. He changed into determined to be bordering insane and as a result his so his conviction of murder was substituted for one in all murder.

Another hassle with the law on diminished duty is that diminished Responsibility covers a extensive range of mental situations which includes paranoia and epilepsy. Some conditions have been recognised for years, however some of the conditions have been known more recently consisting of ‘battered female syndrome’ which changed into confirmed within the case of Hobson (1998). In this case the defendant stabbed her alcoholic and abusive companion to dying in 1992, throughout a controversy. At the trial she claimed that she had acted in self-defence, and there was a subsidiary trouble on provocation. Diminished obligation was no longer specially raised and the defendant become convicted. She appealed at the grounds of diminished responsibility based on battered female syndrome which formerly turned into now not appeared as abnormality of mind till 1994. The Court of Appeal allowed the attraction and ordered a retrial. The hassle with this vicinity of law is that some conditions are not regarded as abnormality if thoughts till afterward and so the development in this location of regulation could be very slow which results in humans who’ve a proper circumstance being punished for something that they had no manage over.

The Abnormality of thoughts ought to be caused by one of the topics set out within the brackets within phase 2 (1) of the Homicide Act 1957. These are: a situation of arrested or retarded development of thoughts, any inherent reason, triggered via any disease or injury. Inherent reason means one that comes from in the defendant, instead of an out of doors thing and it does now not must be everlasting. The vital factor is that there must be clinical proof given at the trial, of an abnormality of thoughts arising from one of the specified causes.The abnormality of the thoughts must be together with to drastically impair the defendant’s duty for his movements. In Lloyd (1967) it was held that ‘substantial’ does not imply ‘general’, nor did it imply ‘trivial’ or ‘minimum’. It is some thing in between and it’s far as much as the jury to determine if the defendant’s mental obligation changed into impaired and if so, changed into it appreciably impaired? In seers (1984) the court additionally considered the word ‘substantially impaired’ and held that ‘considerably’ way extra than ‘trivial’ but not ‘total’ or ‘absolute’ impairment.

Diminished obligation and alcohol makes things extra complex as there are various combinations of intoxication and dwindled obligation that need to be taken into consideration that are: intoxication handiest, intoxication and a pre-existing abnormality of mind no longer related to the intoxication, intoxication which has brought on mind damage and intoxication due to dependency/addiction.There is a clear rule that intoxication alone isn’t Diminished responsibility. In Di Duca (1959) – The court docket of attraction held that the immediate results of taking alcohol or capsules were not an damage, even if it did have an impact on the mind. So a ‘brief’ country of intoxication turned into no longer an abnormality of mind.


There are also difficulties in cases in which the defendant has some abnormality of thoughts but, in addition, is intoxicated on the time he does the killing. This problem become taken into consideration in Gittens (1984). In this case the defendant was stricken by depression. During a go to home from health facility he argued with his spouse and beat her to demise after which raped and killed his stepdaughter. At the time of the offence he have been drinking and taking drugs for despair. The jury had to take into account all of the factors aside from the intoxication and see if it amounted to a enormous impairment of the defendant’s obligation for his acts. The selection was interpreted as that means that the defendant should best prove diminished obligation if he should satisfy the jury that he could have killed because of the abnormality of mind even supposing he had not been intoxicated.

This point become later confirmed by using Dietschmann (2003). In this situation the defendant killed a person in a savage attack while he changed into very under the influence of alcohol. He became also suffered from a mental abnormality, particularly an adjustment sickness which changed into a depressed grief response following the demise of his aunt, Sarah, with whom he had a close emotional and bodily relationship and whom he (wrongly) believed had dedicated suicide due to her drug issues. It became held that to benefit from the finding of dwindled responsibility, D does no longer have to reveal he might have killed had he been sober. Also by way of being intoxicated it does no longer entitle the defendant to the gain of the defence of dwindled obligation, the handiest element which the regulation recognises as able to diminishing his intellectual responsibility is the intellectual abnormality defined by the expert witnesses. It turned into also stated that drink is most effective able to amounting to Diminished Responsibility if it both causes damage to the brain or produces an impossible to resist craving in order that intake is involuntary (e.G. Alcohol dependence syndrome)

If the brain has been injured through alcoholism, then that damage or disorder can assist a finding of faded responsibility. This changed into said in Tandy (1989). In Tandy (1989), the defendant, an alcoholic, had under the influence of alcohol almost a bottle of vodka when she instructed her mother that her 11 yr antique daughter was involved with her husband (Tandy’s). So she strangled her eleven year old daughter. (She usually drank Vermouth or Barley wine), the court of enchantment held that where the defendant is unable to face up to drinking, so this is involuntary, this could quantity to diminished responsibility. The same point was taken into consideration again in timber (2008), where the court of attraction mentioned that the ‘sharp impact of the difference drawn in Tandy among cases in which brain damage has passed off due to alcohol dependency syndrome and wherein it has no longer, is no longer appropriate. The court docket of appeal also stated that the jury have to ignore any consumption of alcohol which they decide turned into voluntary. In the case of Wood (2008), the defendant changed into drunk and went to the victim’s house and had fallen asleep. When he woke up he found the sufferer seeking to carry out oral sex on him and hit the victim with a meat smart killing him.

Although dwindled responsibility had furnished a extra nice defence than insanity for defendants who kills however are affected by a mental abnormality, there are nevertheless issues with the defence. One such problem is the burden of evidence as in maximum different cases the defence best has to raise the defence and it’s far as much as the prosecution to disapprove it. At the instant, defendants beautiful faded duty are at a drawback which isn’t always faced by way of the ones elevating provocation.

Another trouble is the wording of section 2 of the Homicide Act 1957. The definition on this has been constantly criticised. Lord Justice Buxton describes the wording as a ‘disgrace’. The regulation commission in its report, homicide, manslaughter and infanticide (2006) pointed out two principle problems with the modern regulation. These were that the segment does now not provide an explanation for what is worried in ‘considerably impairment of intellectual responsibility’ and that the definition in phase 2 become no longer drafted with the needs and practices of health workers in mind.


There had been also many proposals for reform. For instance the Butler Committee advocated setting the burden of proving that the defendant did the act (or made the omission) with the considered necessary kingdom of thoughts, at the prosecution. The purpose behind the Committee’s thought seems to have been the perceived anomaly of the issue of burden of evidence in relation to the defences of insanity and diminished responsibility. The Criminal Law Revision Committee additionally felt that the prosecution have to bear the burden of disproving madness and dwindled responsibility. They felt that, but glad attorneys may be with the distinction between being certain and being glad at the balance of chances (adding “if indeed any are”), juries are probable harassed by those subtleties and through the exceptional setting of the load of proof for one of a kind offences. The Criminal Law Revision Committee expressed their confidence within the judges to ensure that defences which don’t have any right foundation at the evidence are withdrawn from the jury.

The Butler Committee additionally encouraged that it have to be viable, where the prosecution are in possession of proof indicating that a defence under the segment can be made out, for them to rate manslaughter in the first instance in preference to homicide. The Committee stipulated that the prosecution could be likely to undertake this direction only whilst it’s miles clean that the defence had been agreeable to it. If the defence wanted to resist proof of intellectual sickness the price should be homicide as is currently the case.

The Criminal Law Revision Committee have recommended the Butler Committee’s recommendation, being of the opinion that the mental situation of a disturbed person isn’t always in all likelihood to be improved via having a charge of homicide super. They additionally felt that it can’t be right that costs need to be favored within the most solemn way regarded to the law, i.E. On indictment, when the prosecution understand that there may be a defence to the fee which is possibly to succeed. In this the Criminal Law Revision Committee had the help of several distinguished public bodies.

This recommendation, but, has not been enacted in the Bill. Sparing the defendant from the tension of getting a tribulation for homicide pending and from the anguish of performing in court docket on a murder rate might have given expression to the muse of humanity on which the defence is based totally. Only cases where the clinical evidence become contested with the aid of the prosecution could be attempted as homicide. Thus valuable court docket time and cost could had been saved as judges might no longer be faced with protracted medical testimony on the problem of faded obligation earlier than finding out whether or no longer to accept the plea or to leave it for jury determination. This leads me to conclude that sure the law on diminished duty is certainly first-class.
