Is an order the same as an opinion? No.
An Order is a final ruling on an issue in a case, usually in the trial court. An opinion, generally is from an appeals court and outlines the reasons for a decision.
When a judge issues an order, it is a directive from the bench for someone to do something. For example, if a judge orders someone to appear before the court on a certain date and time, that person is required to appear. If the person does not have a valid excuse for failing to do so, the person is in comtempt of the court's order. If one is in contempt of a state court order, the judge would be allowed to direct the sheriff to execute or enforce the order. If one is in contempt of a federal court order, the judge could direct the marshalls to enforce.
Not all opinions contain orders and most orders do not contain opinions, they're orders.
