§ 505 Demurrer to indictment or information, requisites of.

Here's a plain English summary of this rule:

If someone charged with a crime wants to challenge the indictment or information (the formal document listing the charges), they can file what's called a demurrer. This is basically a legal objection saying there's something wrong with how the charges were written up.

To make this objection count, it has to follow certain steps. The demurrer must be written down, not just spoken in court. Either the defendant or their lawyer has to sign it, and it needs to be filed with the court.

The most important part is that the demurrer has to clearly explain exactly what's wrong with the charges. A vague complaint won't work. If the person doesn't spell out specific reasons for their objection, the court will simply ignore it. This rule makes sure that judges know exactly what problem they're being asked to look at, and it gives the prosecution a fair chance to respond to a clear complaint rather than guessing what the issue might be.
