Well, in the case of family court, it can establish paternity if a mother (or father for that matter) is trying to sue for custody, child support, etc.
In cases of sexual harassment, murder, theft, breaking & entering, DNA can prove guilt if there is hair, blood, skin cells, etc. left behind at the scene of the crime.
DNA can't lie, so if there is a case where the DNA is a positive match to a suspect, it is almost always certain that the suspect is guilty of the crime.
However, there can be circumstances which make the suspect innocent. Such as, for example, in case of sexual harassment, the suspect had sexual intercourse with the victim prior to the assault (within a certain amount of time). In the case of murder or theft where blood or hair was found at the scene of the crime, if the suspect had been there prior to the incident and injured him/herself, there could have been blood left at the scene and hair could have been left just from being there.
Therefore, DNA is extremely important in court, however so are the facts.
DNA is vital in all investigations. In a criminal case it can determine if someone was present at the science of a crime and if they actual committed the crime.
