Common law offences, also known as judge-made crimes, are crimes that are not defined by statute but have developed over time through judicial decisions and precedents. Common law crimes are rooted in the common law legal system, which originated in England and has influenced the legal systems of countries including the US, Canada, and Australia. Common law crimes are often defined by their essential elements and legal principles, and they continue to shape the criminal justice systems of many countries, often coexisting with statutory offences. The constant evolution of common law means that lawyers must stay on top of case law developments.

Common law offences are vague and open to development
Common law offences, also known as judge-made crimes, are those that are not defined by statute but have evolved over time through judicial decisions and precedents. They are rooted in the common law legal system, which originated in England and has influenced the legal systems of many countries, including the United States, Canada, and Australia. Common law offences are often viewed as vague and open to development, as they are not precisely defined by statute but are shaped by judicial interpretations and evolving societal values.
The vague nature of common law offences can lead to debates about fairness and predictability in the legal system. As they rely on judicial decisions, there may be ambiguity in their definitions, and their application can vary across cases and jurisdictions. This ambiguity can be problematic, particularly when it comes to the principle of certainty in the law. For example, in England and Wales, the Law Commission aimed to abolish all remaining common law offences, replacing them with offences defined by statute. The Law Commission viewed common law offences as unacceptably vague and open to development by courts in ways that might violate the principle of certainty.
However, it is important to note that common law offences have not been entirely abolished in England and Wales, and some still exist today. This is because the Law Commission and UK Parliament have not completed the necessary revisions to replace all common law offences with statutory offences. The constant evolution of common law means that criminal lawyers must stay up-to-date with case law developments, as interpretations and applications of the law can change over time.
The flexibility of common law offences allows the criminal justice system to adapt to changing circumstances while relying on established legal principles. This balance between tradition and addressing contemporary issues is reflected in the coexistence of common law and statutory offences in many legal systems. For example, in modern legal systems, common law crimes coexist with statutory crimes that address emerging forms of criminal behaviour, such as cybercrime and environmental offences.
In summary, common law offences are vague and open to development as they are shaped by judicial decisions and evolving societal values rather than being defined by statute. While this flexibility allows the law to adapt to changing circumstances, it can also lead to debates about fairness and predictability in the legal system. The ongoing evolution of common law offences highlights the importance of staying current with case law developments and interpretations.

Common law offences are judge-made crimes
Common law offences, also known as judge-made crimes, are crimes that are not defined by statute but have evolved over time through judicial decisions and precedents. These crimes are rooted in the common law legal system, which originated in England and has influenced the legal systems of many countries, including the United States, Canada, and Australia. Common law crimes have developed over centuries as judges made decisions in individual cases, establishing legal precedents. These decisions were based on common sense, traditional notions of justice, and evolving societal values. As cases accumulated, legal principles emerged that defined what constituted criminal conduct.
Common law crimes are often defined by their essential elements and legal principles. For example, the crime of murder in Michigan is not defined by statute, but the penalties for it are. The elements and meaning of murder are entirely set out in case law. This means that the crime of murder is a judge-made crime, developed through judicial decisions and precedents over time.
The constant evolution of common law means that criminal lawyers must stay on top of case law developments. Common law crimes are often ambiguous in their definitions, and their application can vary between cases and jurisdictions. This can lead to debates about fairness and predictability in the legal system. However, precedent plays a crucial role in maintaining consistency and predictability in the application of common law crimes. Courts frequently refer to previous decisions when determining the outcome of new cases.
In modern legal systems, common law crimes often coexist with statutory crimes, reflecting a balance between tradition and the need to address contemporary issues. While common law crimes provide flexibility and adaptability, statutory offences are created by legislation to address specific issues, such as cybercrime and environmental offences. In England and Wales, the Law Commission aimed to abolish all remaining common law offences and replace them with offences defined by statute. However, this has not been completed, so some common law offences, such as abduction, assault, rape, and robbery, still exist and are punishable by unlimited fines and imprisonment unless a specific maximum sentence has been codified.

Common law offences are inconsistent with the prohibition of ex post facto laws
Common law offences are crimes that are defined by prior judicial decisions or case law rather than being explicitly outlined in criminal codes or statutes. Common law is in a constant state of evolution, with new decisions from higher courts shaping the interpretation and application of the law.
In contrast, ex post facto laws are those that retroactively apply to criminalise actions that were not illegal when they were committed or increase the severity of punishment for an offence after it has been committed. The Latin legal principle "Lex retro non agit" ("A law does not apply retroactively") encapsulates the prohibition of such retroactive laws.
The inconsistency between common law offences and the prohibition of ex post facto laws arises from the inherent uncertainty and vagueness associated with common law. Common law offences are often criticised for being open to interpretation and development by courts, potentially conflicting with the principle of legal certainty. This dynamic nature of common law may result in the criminalisation of actions that were previously lawful or the imposition of more severe penalties, inadvertently violating the prohibition of ex post facto laws.
For example, in the United States, the Criminal Justice Act 2003 retroactively allowed for the retrial of individuals acquitted of murder and certain other serious offences if new and compelling evidence emerged. This Act was criticised for effectively abolishing the prohibition against ex post facto laws and double jeopardy. Similarly, in Australia, legislation has been passed to retrospectively prosecute unethical tax avoidance schemes and certain war crimes, raising concerns about the constitutional separation of powers.
To address these inconsistencies, some jurisdictions have taken steps to abolish or codify common law offences. For instance, the Law Commission in England and Wales aimed to replace common law offences with precisely defined statutory offences, although this process remains incomplete. Other countries, like New Zealand, have abolished the ability to initiate criminal proceedings based solely on common law, except for specific exceptions like contempt of court.

Common law offences are punishable by unlimited fines and imprisonment
Common law offences are crimes under English criminal law, as well as the criminal law of some Commonwealth countries and US state laws. These offences are developed entirely by the law courts and have no specific basis in statute law.
Common law offences are viewed as unacceptably vague and open to interpretation by the courts, which may conflict with the principle of certainty. As a result, England and Wales have aimed to abolish these offences, replacing them with offences defined by statute. However, as this process is not complete, some common law offences remain. These include obstruction of justice, perverting the course of justice, defeating the ends of justice, and obstructing the administration of justice.
In England and Wales, common law offences are punishable by unlimited fines and imprisonment unless a specific maximum sentence has been codified. The court considers the offender's "means" when deciding on the imposition of a fine, taking into account their income and expenditure. While Scotland has provisions for unlimited fines in common law offences, it also specifies maximum fine amounts for certain types of offences.
The situation regarding common law offences varies across US states. Some states, like New Jersey, have abolished common law crimes, while others continue to recognize them. In some states, crimes are defined primarily or entirely by common law, with penalties outlined in statutes. For example, while Michigan's penal code does not define murder, it does lay out the penalties for this crime.

Common law offences include choking or strangulation, and obstruction of justice
Common law offences are crimes or offences that are defined by prior judicial decisions or case law rather than being explicitly outlined in criminal codes or statutes. In England and Wales, common law offences are punishable by unlimited fines and unlimited imprisonment unless a specific maximum sentence has been codified. While some jurisdictions have abolished common law crimes, others continue to recognize them.
Strangulation, on the other hand, is addressed under Section 75A of the Serious Crime Act 2015 (SCA 2015). It is defined as the application of force or pressure by the defendant to the victim's neck, using their hands or other means, to stop respiration by compressing the air passage. This offence applies when strangulation does not result in the death of the victim and does not require proof of consequences such as impeded breathing.
Obstruction of justice, perverting the course of justice, defeating the ends of justice, and obstructing the administration of justice are also considered common law offences. These offences relate to interfering with the legal process or the administration of justice, which can include actions such as witness tampering, evidence tampering, or influencing jurors.
It is important to note that the specific definitions and penalties associated with these offences may vary depending on the jurisdiction and the evolution of common law over time.
