In such systems, the person bringing the charges must pay damages if the charges don't stick. Remember, the bar for criminal conviction is much higher than in civil court, and anyone can bring a civil case in our current legal system.

One major flaw in our current system is that only the government decides who gets convicted and as the old adage goes, if the king controls criminal punishment, the kings friends get away with murder. Think about the current national conversation on excessive police brutality.
