NCAT cases are usually internal to a scheme — by-laws, levies, repairs, access to records. Court cases usually involve builders or insurers over defects, because those claims exceed the tribunal's jurisdiction. These are published decisions only — most strata disputes settle or are resolved without a judgment, so this is a floor, not a count. See the Dee Why suburb profile.
