What is The code for crown prosecutors?

The Code for Crown Prosecutors is a public document, issued by the Director of Public Prosecutions that sets out the general principles Crown Prosecutors should follow when they make decisions on cases. Is there enough evidence against the defendant? When deciding whether there is enough evidence to charge, Crown Prosecutors must consider whether evidence can be used in court and is reliable. Crown Prosecutors must be satisfied there is enough evidence to provide a "realistic prospect of conviction" against each defendant. Is it in the public interest for the CPS to bring the case to court? A prosecution will usually take place unless the public interest factors against prosecution clearly outweigh those in favour of prosecution
