Looks like an exparte order for civil suit. If you did not recieve notice of summons its a serious lapse of legal principle.
First i would verify the judgement. How did you come to find about the fine? Couldn't the same channel be used for summons? Also notice of summons are served 2 times more or less in my jurisdiction at least.
See legal portal or go ask the Court for the copy.
After that seek a small time run of the mill attorney, they shall be better suited to give you advise.
And you can be held liable for defamation over the internet. The order/judgement will tell you the reasons why, so first verify the judgement first.
This is not a legal Advise. Please talk to a attorney.
