If you're appealing a habeas corpus case in Alabama, the rules that apply depend on what kind of case it is. For most habeas corpus appeals, you follow the process laid out in state law under Code of Alabama Section 12-22-90. This is a separate law that spells out the specific steps for these types of appeals.
However, there's an exception for child custody cases. If your habeas corpus case involves who gets custody of a child, you don't follow the special habeas corpus process. Instead, you follow the same rules that apply to regular civil case appeals. This means the standard appellate procedures, like deadlines for filing and how to present your case, will apply just as they would in any other civil appeal.
