His detractors truly asserted that he rejected a greater number of important bills than all the Kings of the House of Stuart put together, and most absurdly inferred that the sense of the Estates of the Realm was much less respected by him than by his uncles and his grandfather.

A judicious student of history will have no difficulty in discovering why William repeatedly exercised a prerogative to which his predecessors very seldom had recourse, and which his successors have suffered to fall into utter desuetude.
His predecessors passed laws easily because they broke laws easily.
Charles the First gave his assent to the Petition of Right, and immediately violated every clause of that great statute.

Charles the Second gave his assent to an Act which provided that a Parliament should be held at least once in three years; but when he died the country had been near four years without a Parliament.

The laws which abolished the Court of High Commission, the laws which instituted the Sacramental Test, were passed without the smallest difficulty; but they did not prevent James the Second from reestablishing the Court of High Commission, and from filling the Privy Council, the public offices, the courts of justice, and the municipal corporations with persons who had never taken the Test.

Nothing could be more natural than that a King should not think it worth while to withhold his assent from a statute with which he could dispense whenever he thought fit.
The situation of William was very different.
