>That's up to the person for the particular role. Imagine hiring a nanny and some bureaucrat telling you what prior arrest is "relevant". No thanks. I'll make that call myself.

Thanks, but I don't want to have violent people working as taxi drivers, pdf files in childcare and fraudsters in the banking system. Especially if somebody decided to not take this information into account.

Good conduct certificates are there for a reason -- you ask the faceless bureaucrat to give you one for the narrow purpose and it's a binary result that you bring back to the employer.
