2. CRIMINAL LAW
 Criminal law is the body of law that relates to crime. It
regulates social conduct and prescribes whatever is
threatening, harmful, or otherwise endangering to the
property, health, safety, and moral welfare of people. It
includes the punishment of people who violate these
laws. Criminal law varies according to jurisdiction, and
differs from civil law, where emphasis is more on dispute
resolution and victim compensation than on punishment.

3. PROSPECTIVE (Prospectivity) – the law does not have any retroactive
effect

ACTUS REUS| MENS REA | CONCURRENCE| CAUSATION| RESULTING
INJURY OR CRIME

9. ACTUS REUS, PHYSICAL ACT OF THE CRIME
 DEFINITION:
 A guilty act that is conscious and voluntary.
“Are we going to hold somebody criminally liable for an act that is not
volitional and not voluntary?”
NO, WE’RE NOT.

10. ACTUS REUS, PHYSICAL ACT OF THE CRIME
 EXAMPLES:
Someone who is driving a car suddenly had a heart attack and they
hit somebody along the sidewalk. Are they going to be guilty of hitting
somebody?
NO.
A person who has a sleep walking disorder commits murder. Are they
going to be found guilty of the crime?
NO.

11. OMISSIONS TO ACT
 GENERAL RULE:
 No duty to action on behalf of a stranger in peril.
EXCEPTIONS:
1. BY LAW
Sometimes, there are duties to act that are prescribed by law.
EXAMPLE:
You have a duty to automatically pay your taxes. If you don’t, you
could be held liable for tax evasion.

12. OMISSIONS TO ACT
2. BY CONTRACT
When you are contracted by duty to come to the aid of another.
EXAMPLE:
A lifeguard in a pool is being paid to rescue and save people. But then
the lifeguard was just sitting there flirting with a cute girl whilst someone
was drowning.
If the victim then drowns, we can hold the lifeguard guilty of involuntary
manslaughter for his failure to fulfill his contract.

Relationships may also impose a duty to act.

14. MENS REA, MENTAL INTENT TO DO THE CRIME
 DEFINITION:
 A guilty mind.

WHERE TO FIND MENS REA?
1. Specific Intent Crimes
2. General Intent Crimes
3. Strict Liability Crimes

15. MENS REA, SPECIFIC INTENT CRIMES

4. Mayhem
5. Depraved Heart Murder

17. MENS REA, STRICT LIABILITY CRIMES

committed the prohibited act.
EXAMPLES:
1. Speeding
2. Parking in front of a fire hydrant
3. Statutory rape

18. CONCURRENCE, OF ACTUS REUS AND MENS REA
 DEFINITION:

committed the crime.
CAUSATION
 GENERAL RULE:
 You only need to go to causation when there’s a third party that’s involved
or an act of God.
“Is the defendant the legal or the proximate cause of the resulting crime or
injury?”

19. CLASSIFICATION OF
CRIMES
FELONIES | MISDEMEANORS | MALUM IN SE CRIMES | MALUM
PROHIBITUM | INFAMOUS CRIMES

20. FELONIES
 DEFINITION:
 Crimes that are generally punishable by death, or imprisonment
exceeding one year.
 A felony that's punishable by death is considered a capital crime.
 EXAMPLES:
 Burglary
 Rape
 Arson

22. MISDEMEANORS
 Whether a crime is considered a felony or a
misdemeanor will many times depend on any
aggravating factors. These are factors that make a
crime more serious. For example, the theft of a very
inexpensive item from a store may be considered a
misdemeanor. However, the theft of multiple items that
are worth thousands of dollars may be considered a
felony.

23. MALUM IN SE, EVIL IN ITSELF
 DEFINITION:

 Mail and Securities Fraud

27. THEORIES OF
CRIMINAL LAW
CLASSICAL THEORY | POSITIVIST THEORY | ECLECTIC OR MIXED

28. CLASSICAL THEORY, JURISTIC
 Man is essentially a moral creature with an absolute free will to
choose between good and evil and therefore more stress is placed
upon the result of the felonious act than upon the criminal himself.
 The purpose of penalty is retribution.
 Man is regarded as a moral creature who understands right from
wrong. So that when he commits a wrong, he must be prepared to
accept the punishment therefore.

29. POSITIVIST THEORY, POSITIVIST
 Man is subdued occasionally by a strange and morbid
phenomenon which conditions him to do wrong in spite of or
contrary to his volition.
 The purpose of penalty is reformation.
 There is great respect for the human element because the offender
is regarded as socially sick who needs treatment, not punishment.
Crimes are regarded as social phenomena which constrain a
person to do wrong although not of his own volition

30. ECLECTIC OR MIXED PHILO, GROTIANS
 This combines both positivist and classical thinking. Crimes that are
economic and social and nature should be dealt with in a
positivist manner; thus, the law is more compassionate. Heinous
crimes should be dealt with in a classical manner; thus, capital
punishment.

31. STAGES IN THE COMMISSION
OF THE CRIME
INTENTION TO COMMIT THE CRIME| PREPARATION TO COMMIT CRIME
| ATTEMPT TO COMMMIT THE CRIME | COMMISSION OF THE CRIME

33. INTENTION TO COMMIT THE CRIME
 Guilty mind to commit the crime. Intention to commit a crime is not
punishable unless it is made known to others either by words.
PREPARATION TO COMMIT THE CRIME
 Arranging for the means and measures necessary for the
commission of the crime. Preparation is not normally
punishable. However, there are some exceptions:
o Waging war against government
o Preparation for counterfeiting coins and government stamps, etc.

34. EXAMPLE OF PREPARATION
 ‘A’ intends to kill ‘B’.’A’ purchases poison in order to mix with B’s
food. Up to this stage, A’s act is mere preparation.
EXAMPLE OF AN ATTEMPT
 ‘A’, a pick pocket puts his hand in B’s pocket to steal the purse of ‘B’
but ‘A’ does not find any purse in B’s pocket. Is it a crime?
Yes, it is a crime of attempt to theft.

35. ATTEMPT TO COMMIT THE CRIME
 Attempt is the direct movement towards the commission of an offense
after the preparation has been made. Attempt is those acts, which
cross the stage of being preparatory to the commission of an offense.
COMMISSION OF THE CRIME
 If the attempt to commit the offense is successful, then the crime is
committed .
EXAMPLE:
‘A ‘fired at ‘B’ with the evil motive to kill ‘B’ and B died immediately. This is the
crime of murder. This stage is the commission of the crime.

36. PENALTIES
RECLUSION PERPETUA| RECLUSION TEMPORAL| PRISIÓN MAYOR |
PRISIÓN CORRECCIONAL | ARRESTO MAYOR | ARRESTO MENOR

38. PARTICIPATION OF THE
OFFENDER
PRINCIPALS| ACCOMPLICES| ACCESSORIES

39. PRINCIPALS
 A persons can be liable as a principal for:
 taking a direct part in the execution of the felony,
 directly forcing or inducing others to commit it, or
 cooperate in the commission of the offense by another act
without which it would not have been accomplished.

40. ACCOMPLICES
 Accomplices are persons who, while not acting as a principal, cooperate in
the execution of the offense by previous or simultaneous acts.
ACCESSORIES
 Accessories are those who, having knowledge of the commission of the
crime, and without having participated therein, either as principals or
accomplices, take part subsequent to its commission by:
 profiting themselves or assisting the offender to profit by the effects of the crime,
 concealing or destroying the body of the crime, or the effects or instruments
thereof, in order to prevent its discovery, or
 harboring, concealing, or assisting in the escape of the principals of the crime.
