Case (or judicial opinion) citations follow a common structure, whether from a federal or state court. They include:

General Guidelines
Legal citations are less concerned with format or location when citing sources.
The Blue Book recommends that you provide a URL if it will make it easier to find the source.
Add the URL to the end of the citation, followed by a period:
