Just to be on the safe side I moved the zip attachment to Linux before opening. There is an exe file inside. I suspect this is a dangerous file and not from any court persons. Firstly it seems strange you would be notified by email instead of via registered postal mail. Secondly, the document should be a readable file such as a PDF or text document. Instead the file is an exe which is no doubt a hoax and potentially very dangerous script file 'probably' used for identity theft or to steal banking details or in some other way take control of your computer.

At this point I have not researched the two senders (both with different non-related email addresses which do not appear to be from any court jurisdiction or legal group) but will do that later.

Also in replying to the 2nd email to you, it warned I was attempting to attach a file before sending. Dangerous emails it seems.

So in summary at this point in time, ignore those emails, evidence points to a hoax and was spam.
