Where a plaintiff serves a declaration together with summons as provided for in Rule 113, the dies induciae for entering appearance to defend is 20 days (comprising the normal 10 days under Rule 17 plus an additional 10 days under the proviso to Rule 119), not the ordinary 10 days applicable when summons is served without the declaration. A default judgment obtained before the expiry of this 20-day period is premature and liable to be rescinded. The general rule that costs follow the event applies, and a party may be ordered to pay costs where it has put the other party to unnecessary expense by insisting on defending an indefensible position, notwithstanding a subsequent consent to judgment.
