"(i) a judgment signed in default is a regular judgment from which, subject to (ii) below, the plaintiff derives rights of property;
(ii) the Rules of Court give to the Judge a discretionary power to set aside the default judgment which is in terms 'unconditional' and the Court should not 'lay down rigid rules which deprive it of jurisdiction';
(iii) the purpose of this discretionary power is to avoid the injustice which might be caused if judgment followed automatically on default;
(iv) the primary consideration is whether the defendant 'has merits to which the court should pay heed', not as a rule of law but as a matter of common sense, since there is no point in setting aside a judgment if the defendant has no defence and if he has shown 'merits' the 'Court will not, prima facie, desire to let a judgment pass on which there has been no proper adjudication';
(v) again as a matter of common sense, though not making it a condition precedent, the Court will take into account the explanation as to how it came about that the defendant '... found himself bound by a judgment regularly obtained to which he could have set up some serious defence'."
