Difference betwee intervening and consolidating cases
It is not the victim's responsibility to bring a criminal case.
In a kidnapping case, for instance, the government would prosecute the kidnapper; the victim would not be a party to the action.
The government, on behalf of the people of the United States, prosecutes the case through the United States Attorney's Office if the person is charged with a federal crime.
A state's attorney's office prosecutes state crimes.
In some criminal cases, there may not be a specific victim.
For example, state governments arrest and prosecute people accused of violating laws against driving while intoxicated because society regards that as a serious offense that can result in harm to others.
Consolidation is used in technical analysis to describe the movement of a stock's price within a well-defined pattern of trading levels.
