imposed, and its severity, is in large part determined by the degree of fault shown by the defendant. This can also be seen in the impact of both aggravating and mitigating factors. This is why some people are opposed to the use of minimum and mandatory sentences, as they break the relationship between the degree of fault present in the offence committed and the sentence imposed. A guilty plea can have an effect on the sentence, depending on when it is made. Making a guilty plea before the start of the trial can reduce the sentence imposed by up to one third but changing the plea to guilty once the trial has started can only reduce it by one tenth. This is because admitting fault after the trial has begun has wasted court time and money (for jury and judge etc.), so this is reflected in the sentence. Tariffs and minimum sentences also illustrate that fault is relevant to the sentencing process, whether the defendant pleads guilty or is found guilty in court. Types of sentences Types of sentences will also reflect level of blameworthiness: Custodial sentence Suspended sentence Curfew Extended sentence Community sentence Fine Conditional discharge or Absolute discharge Strict liability There is a role for strict liability in criminal law, in relation to both regulatory offences and offences of social danger. It can be argued that the interests of society as a whole can sometimes justify the imposition of liability without fault. Nevertheless, it should be pointed out that the degree of fault still plays an important part in determining the sentence following a conviction Conditions for strict liability Only actus reus needs to be established No blameworthiness is required on the part of the defendant It normally applies to regulatory offences (health and safety, minor traffic offences etc.) The advantages and disadvantages must be considered Cases include Sweet v Parsley (1969) – where the defendant was found guilty of allowing her property to be used for cannabis smoking. Even though she had no knowledge of the offence, it was on her property so she was liable without fault. This conviction was later quashed by the House of Lords on the grounds that knowledge of the use of the premises was essential to the offence. Since she had no such knowledge, she did not commit the offence. Harrow London Borough Council v Shah and another (1999) - relating
