That's not true, the legislature has final say over both statutory and constitutional law; it's just that the barrier to amending the constitution is higher than amending / passing statutory laws. The Court's job is to interpret the law of its jurisdiction. If the legislature doesn't like the Court's ruling on some statutory law, it would then go through the process of amending the law. If the legislature doesn't like the Court's ruling on some constitutional matter, it would then go through the process of amending the Constitution. The latter process usually requires sufficiently more political will that sometimes a Court's ruling on a Constitutional matter is "final" from a practical standpoint.
