I'm not a qualified legal eagle, but have knowledge in this field, and in my experience you do your investigation, make your claim (charges), disclose your evidence to the defendant & agree a timetable for them to respond.
If the parties can't come to a settlement or full settlement, only then do you proceed to the judicial process. Our situation is anything but this, hence why I was confused how this situation was allowed to come about.
The fact the accuser made the claim but estimates it'll take them 2-4 years to provide their evidence suggests to me this is a bullshit fishing exercise meant to damage City's reputation in the court of public opinion.
I'd appreciate it if you can correct me if I've got the non-criminal process wrong somewhere. None of this makes any sense to me outside of what I've stated & reasoned.
