"It is a time honoured principle of law that the jurisdiction of a court to hear a matter or lack of it is a threshold issue and has the character of assuming the focal position in all litigations. The issue of jurisdiction can be raised at any time whether it was pleaded or not. It can be raised by the court "suo motu" and even on appeal as in the instant appeal. It is very fundamental. What it involves is, what will enable a plaintiff to seek a hearing in court over his grievance, and get it resolved because he is able to show that the court is empowered to entertain the subject-matter"
