Civil investigation is the conduct of non – criminal investigations. In Australia we have police who handle all aspects of criminal investigation, and despite what you read in sensationalized headlines, the police are very successful at it.
Non – criminal investigations involve matters such as Insurance, Sexual Harassment, Work Place Bullying and Internal Corporate Investigation.
The differences are police are involved with Criminal law – involving offences against the legislation of the State (e.g. rape, stealing) and this is applied on the criminal burden of proof, “Beyond a reasonable doubt”. The two parties are referred to as: Prosecutor vs Accused, if the accused is found guilty, punishment is determined.
Civil law – involves one person enforcing their private rights against another (e.g. breach of contract). This will be determined by a court, applying the civil burden of proof, “Balance of Probabilities”. The Law of Torts is applied in these matters. The two opposing parties are referred to as: Plaintiff vs Defendant, if Negligence is determined, damages are awarded
