I am having some discussions about this report:

http://www.cps.gov.uk/publications/research/perverting_course_of_justice_march_2013.pdf

It states that

In the period of the review, there were 5,651 prosecutions for rape and 111,891 for domestic violence

And:

This report analyses the 159 charging decisions made over a seventeen month period between January 2011 and May 2012.

(The charging decisions are in reference to charges of false allegations of rape or domestic violence)

I have someone telling me that the number of "charging decisions" represents everyone who alleged that they were falsely accused of rape or domestic violence. That is, anyone who alleged they were falsely accused would automatically result in a "charging decision" for false accusations.

Which if true, then means that only 159 out of 115,000 being prosecuted alleged that they were falsely accused. Which then means that false accusations are very rare, since very few men even allege that they were falsely accused.

That makes no sense to me - surely more than 1 in 800 that would claim that the accusations are false, even if merely as a ploy to beat the rap.

To me, those numbers indicate that the vast majority of men who want to make allegations of being falsely accused are either discouraged by the prosecution, or outright dismissed if they do so.

Can someone who is actually knowledgeable (not just guessing) about this aspect of law shed some light on this?
