The status of a case reflects the changing and dynamic role of the courts as they make legal decisions on problems in the cases before them. A case that contains important statements of the law can be affirmed or overturned in subsequent years. The editors at Westlaw Australia and Lexis Advance use "status symbols" to indicate the current standing of a case. Of course you need to check whether the particular point of law you are researching is still valid or not regardless of the symbol given to the case.
The symbols are hints and warnings but are not statements of law.
