A couple of links that I found, after googling the senders' email addresses:
www.scamwarners.com • View topic - New SPAM - Legal Notice Warning: Obama Personal Law Firm Perkins Coie Fraudulent Court Appearance Email | Obama Birthplace Controversy
And some more general info:
'Notice to Appear in Court" Malware Emails
Don't worry about those emails closeshot - just scumbags at it again
Just remember
never to open any attachments or click on links within an email unless you're sure they are safe
