Nature and Purpose of Criminal Law

Defining a Crime

Card, Cross, and Jones define a crime as:

"…a legal wrong for which the offender is liable to be prosecuted by or in the name of the State, and if found guilty, liable to be punished."

This definition establishes three fundamental legal prerequisites:

1. There must be an act or omission classified as a legal wrong.
2. The offender must be liable to prosecution by the State.
3. The offender must be liable to criminal punishment.

Theoretical Frameworks for Determining a Legal Wrong

To establish what conduct constitutes a legal wrong, jurisprudence relies on three distinct philosophical tests:

1. Legal Moralism:
   • The Test: Does the conduct (or omission) offend the community spirit?
2. The Harm Principle:
   • The Test: Will this conduct (or omission) cause harm or serious offence to others?
3. Paternalism:
   • The Test: Is the conduct (or omission) something from which the offender must be protected?

Where these theoretical perspectives intersect in public policy, conduct is proscribed and formally categorized as a legal wrong.

State Liability and Punishment Characteristics

• Compelling State Interest: For conduct to be prosecuted by the State, there must exist a compelling state interest in prohibiting it.
• State Action Dominance: A criminal prosecution may proceed even if the individual victim has been fully compensated and explicitly requests that the prosecution be discontinued.

Comparative Distinctions: Criminal Law vs. Civil Law

Core Scope of Criminal Law

Criminal law centers on core societal disputes regarding the limits of legal state authority, focusing specifically on:

• Public wrongs
• Prevention of harm to society
• Assigning moral fault
• Determining blameworthiness
• Coercing human behavior through legal sanctions

Relationship Between Law and Morality

Jurisprudential Foundations

The boundaries of legal regulation and moral wrongdoing do not completely overlap. As Lord Atkin observed in Proprietary Articles Trade Association v. A.G. for Canada [1931] A.C. 310 at 324:

"Morality and criminality are far from co-extensive, nor is the sphere of criminality necessarily part of a more extensive field covered by morality."

The Wolfenden Committee Report (1957)

The Report of the Committee on Homosexual Offences and Prostitution (1957) articulated explicit limits on state enforcement of morality, defining the functions of criminal law as follows:

Primary Functions of Criminal Law

• To preserve public order and decency.
• To protect the citizen from what is offensive or injurious.
• To provide sufficient safeguards against exploitation or corruption of others.

Express Exclusions from Criminal Law Scope

• It is not the function of criminal law to intervene in the private lives of citizens or to seek to enforce any particular pattern of behaviour.
• "There must remain a realm of private morality and immorality, which is in brief and crude terms, not the law's business."

Philosophical Models: Libertarian vs. Authoritarian

• The Libertarian View (John Stuart Mill):   > "…the only purpose for which power can be rightfully exercised over any member of a civilized community against his will is to prevent harm to others."

• The Authoritarian View (Sir James Stephen):   > "…there are acts of wickedness so gross and outrageous that… they must be prevented as far as possible at any cost to the offender, and punished… with exemplary severity."

The Devlin-Hart Framework

The debate regarding state enforcement of morality presents two opposing jurisprudential models:

• Lord Devlin:

  • Touted the dangers of a prejudiced, ill-informed majority.
  • Recognized, alongside John Stuart Mill, the necessity of protecting against harms.
  • Rejected the premise that deviation from accepted sexual morality, even by adults in private, is something that inherently threatens the existence of society.

• H.L.A. Hart:

  • Asserted that society may use criminal law to preserve public morality when public feeling rises to "intolerance, indignation and disgust".
  • Maintained that the individual juror ("the man in the jury box") serves as the arbiter of social morality.
  • Posited that there are no theoretical limits to legislation against immorality.

Landmark Common Law Precedents

Shaw v. Director of Public Prosecutions [1962] A.C. 220

• Legal Issue: Whether the courts possess a residual authority to punish conduct tending to corrupt public morals as a common law offense.
• Holding: The Court held that it acts as the custos morum (guardian of morals) of the people.
• Lord Simonds:   > "In the sphere of criminal law I entertain no doubt that there remains in the courts of law a residual power to enforce the supreme and fundamental purpose of the law, to conserve not only the safety and order but also the moral welfare of the State, and that it is their duty to guard it against attacks which may be the more insidious because they are novel and unprepared for…"
• Lord Reid (Dissenting):   > "Some think the law already goes too far, some that it does not go far enough. Parliament is the proper place, and I am firmly of opinion the only proper place, to settle that. When there is sufficient support from public opinion, Parliament does not hesitate to intervene. Where Parliament fears to tread it is not for the courts to rush in."

Knuller Ltd. v. Director of Public Prosecutions [1972] 2 All E.R. 898

• Legal Issue: Whether a conspiracy to encourage or publish material facilitating legal conduct can constitute a criminal conspiracy to corrupt public morals.
• Holding: Conspiracy to corrupt public morals remains a valid common law offense.
• Lord Reid:   > "…there is a material difference between merely exempting certain conduct from criminal penalties and making it lawful in the full sense… I find nothing in the Act to indicate that Parliament thought or intended to lay down that indulgence in these practices is not corrupting. I read the Act as saying that, even though it may be corrupting, if people choose to corrupt themselves in this way that is their affair and the law will not interfere. But no licence is given to others to encourage the practice. So if one accepts Shaw's case as rightly decided it must be left to each jury to decide in the circumstances of each case whether people were likely to be corrupted."

Common Law Approaches in the Caribbean

Chief of Police v. Nias (2008) 73 WIR 201

• Rawlins C.J.:   > "the legislature…has a duty to ensure that basic moral standards of the society are upheld and maintained [and] has determined what use of language offends public morality…the court is in no position to decide when the values of the society require otherwise."
• Edwards J.A. (Ag.) (quoting Lord Devlin):   > "when there ceases to be common belief in the value of the moral code, society is threatened with disintegration"

Dolly Kendall v. Khan (1979) 26 WIR 433

• Crane C.J.:   > "Decency and self-respect ought not… to be enforced by punishment…virtue ought not be secured by legislation but should be inculcated on the minds of the people."
• Quoting Paton:   > "Law in elaborating standards must not try to enforce the good life as such; it must always balance the benefits to be secured by obedience with the harm that the crude instrument of compulsion may do. There are many ethical rules the value of the observance of which lies in the voluntary choice of those who attempt to follow them."

Principle of Legality (Nulla Poena Sine Lege)

Definition and Core Meaning

The Latin maxim Nulla Poena Sine Lege establishes the fundamental principle of legality:

• Literal Translation: "No penalty without a law."
• Legal Rule: Conduct which is not proscribed by law at the time of its commission should not be punished.

Application to Judicial Law-Making (Shaw and Knuller)

The principle of legality creates direct tension with judge-made criminal offenses:

• Shaw v. D.P.P. [1962] A.C. 220:

  • Majority View: The courts, as custodes morum of the populace, retain a residual common law authority to supervise and punish novel offenses prejudicial to public welfare where no statute has intervened.
  • Lord Reid's View: Conspiracy to corrupt public morals existed as an established common law misdemeanour, presenting sufficient evidence for a jury to determine guilt.

• Knuller Ltd. v. D.P.P. [1972] 2 All E.R. 898:

  • Per Curiam: Encouraging conduct that is not itself illegal can still be criminally punished if the conduct is calculated to corrupt public morals, leaving it to the jury to evaluate according to contemporary standards.
  • Lord Reid: Reaffirmed that statutory exemption from criminal penalties does not automatically convert an act into conduct that cannot be regulated when promoted to others.

Aims of Criminal Punishment

Theoretical Objectives: American Law Institute Model Penal Code

Article 1, Section 1.02 of the American Law Institute's Model Penal Code defines five core purposes of criminal law and punishment:

1. To forbid and prevent conduct that unjustifiably and inexcusably inflicts or threatens substantial harm to individual or public interests.
2. To subject to public control persons whose conduct indicates that they are disposed to commit crimes.
3. To safeguard conduct that is without fault from condemnation as criminal.
4. To give fair warning of the nature of the conduct declared to be an offence.
5. To differentiate on reasonable grounds between serious and minor offences.

The Four Primary Rationales of Punishment

1. Retribution:

   • Biblical Justification: Leviticus 24:17–22:      > "When one man strikes another and kills him, he shall be put to death. Whoever strikes a beast and kills it shall make restitution, life for life…fracture for fracture, eye for eye, tooth for tooth…"
   • Social Justification: Forestalls the need for private vengeance and retaliatory self-help by providing institutionalized state punishment.

2. Restraint (Incapacitation):

   • Mechanism: Offenders are physically separated from the rest of society to prevent them from committing additional offenses.
   • Objective: Focused directly on preventing future offending.
   • Systemic Caveat: Prioritizing restraint often leads to the imposition of disproportionate custodial sentences.

3. Rehabilitation:

   • Mechanism: Provides offenders with necessary social, educational, or vocational training.
   • Objective: Re-socializes individuals to enable them to conform their behavior to law-abiding standards upon release.

4. Deterrence:

   • Mechanism: Discourages potential offenders from engaging in criminal activity by making explicit, punitive examples of actual offenders.
   • Scope: Encompasses both individual deterrence (discouraging the specific offender) and general deterrence (discouraging the broader public).

Sources of Caribbean Criminal Law

Caribbean criminal jurisprudence derives its binding authority from four distinct primary sources:

1. The Written Constitution

• Functions as the ultimate supreme source of legal power and constitutional authority within each regional jurisdiction.
• Establishes the fundamental rights, freedoms, and structural legal principles governing society.
• Incorporates a Savings Law Clause, which raises critical constitutional questions:
  • Does the savings clause merely codify existing pre-independence rights?
  • How does the savings clause impact constitutional challenges to historical sanctions, such as the mandatory death penalty?

2. Legislation

• Reflects the democratically expressed will of the people through Parliament.
• Serves as the primary statutory instrument for legal reform, policy innovation, and codification.

3. Common Law

• Stare Decisis: Judicial adherence to binding precedent established by superior courts.
• Obiter Dicta: Judicial statements made in court rulings that serve as persuasive authority across Caribbean jurisdictions.

4. International Law

• Comprises international treaties, conventions, and customary rules of international law that inform domestic statutory interpretation and regional human rights jurisprudence.
