to serve on the defendant such notice, and such particulars of or relating to the evidence, as may be prescribed.
(3) The rules may provide that the court or the defendant may, in such circumstances as may be prescribed, dispense with a requirement imposed by virtue of paragraph (2).
(4) In considering the exercise of its powers with respect to costs, the court may take into account any failure by a party to comply with a requirement imposed by virtue of paragraph (2) and not dispensed with by virtue of paragraph (3).
(5) Nothing in this Article prejudices the generality of any statutory provision conferring power to make rules of court; and no particular provision of this Article prejudices any general provision of it.
