Attachments are writs directing a law enforcement officer to take possession of property. So the court combined the two legal theories into one, and screened the facts of DeVaney's case through the combined claim. DeVaney won, because in its own case, Thriftway refused to deliver the documents that DeVaney could have used to prove himself correct and because Thriftway should have known it didn't have probable cause to sue. This was new law for New Mexico, although not for many other states. In DeVaney's case, Supreme Court justices cleared things up a little.
