Step 1: Understanding the Concept:
The question asks to identify areas of law where 'mens rea' (a guilty mind) is not required to establish an offence. These are known as 'strict liability' offences. In such cases, the commission of the prohibited act ('actus reus') alone is sufficient for conviction.
Step 2: Detailed Explanation:
The general rule in criminal law is that mens rea is required. However, the legislature can create offences of strict liability, particularly in cases involving public welfare, safety, and regulation.
- (A) Revenue Acts: Offences under taxation and revenue laws (like smuggling under customs law, or tax evasion) are often treated as strict liability offences to ensure effective collection of revenue and prevent economic harm to the state.
- (B) Public Nuisance: Offences related to public nuisance (e.g., selling adulterated food, causing pollution) are classic examples of public welfare offences where the harm to the public is the primary concern, and the defendant's state of mind may be considered irrelevant.
- (C) Criminal case which are in summary mode: The mode of trial (summary or regular) does not determine whether mens rea is required. Many minor offences tried summarily are strict liability (e.g., most traffic violations), but not all. However, it's a common feature of many petty offences tried this way. Given the other clear examples, this option contributes to the overall theme.
Considering that offences under Revenue Acts and those of Public Nuisance are well-established categories of strict liability, and many summary trial cases also fall into this category, 'All of these' is the most appropriate answer, indicating a general trend in these areas.
Step 3: Final Answer:
Offences under Revenue Acts and acts constituting Public Nuisance are classic examples of strict liability where mens rea is not an essential ingredient. Many summary cases also deal with such offences. Therefore, option (D) is the most suitable answer.
