What period applies to defence after jurisdiction challenge?
28 days after final determination unless another period is specified. Serve the defence on every other affected party. The unsuccessful-challenge event replaces the ordinary two-anchor defence model.
Responsible actor. Defendant whose qualifying jurisdiction application failed.
Final determination dismissing the Order 12 rule 8 application or making no order
28 days after final determination unless another period is specified
Defendant whose qualifying jurisdiction application failed. Actual Order 12 rule 8(1) or (2) application; Dismissed or no order made; Final determination established; No different court period. An adjournment or successful challenge is not the final unsuccessful determination required by Order 18 rule 2(3).
Rules of the High Court (Cap. 4A), Order 18, rule 2(3)How does this provision count time?
- Serve the defence on every other affected party
- Defendant whose qualifying jurisdiction application failed uses the established final determination dismissing the order 12 rule 8 application or making no order. 28 days after final determination unless another period is specified. Exclude the effective event day. Ordinary intervening weekends remain counted unless an applicable source provision excludes them. High Court Ordinance (Cap. 4), section 31(1), omits Summer Vacation for the applicable civil procedural period not exceeding one month unless the Court directs otherwise. Order 64 rule 1 supplies August 1 through August 31. Order 3 rule 3 separately covers pleading periods.
- Serve the defence on every other affected party. An office calendar does not automatically change this service, deemed-event, minimum-interval or status boundary. The source and the actual completion route control. The unsuccessful-challenge event replaces the ordinary two-anchor defence model.
- The unsuccessful-challenge event replaces the ordinary two-anchor defence model.
- A closed interparty or combined endpoint needs separate source qualification. An ordinary weekday calculation does not certify this boundary.

The source and the actual completion route control. The unsuccessful-challenge event replaces the ordinary two-anchor defence model. This closed interparty or combined filing and service boundary is withheld pending separate qualification of section71 and the applicable Court procedure. The calculator refuses that boundary.

Questions about this procedure
What period applies to defence after jurisdiction challenge?
Does filing a jurisdiction challenge start defence time?
No. Rule 2(3) uses final determination when the application is dismissed or no order is made.
Rules of the High Court (Cap. 4A), Order 18, rule 2(3)Is an adjourned challenge a final determination?
No. An unresolved or adjourned application does not establish this source event.
Rules of the High Court (Cap. 4A), Order 18, rule 2(3)Does a successful challenge leave the ordinary defence clock running?
This branch only concerns dismissal or no order. The successful order must be reviewed on its own terms.
Rules of the High Court (Cap. 4A), Order 18, rule 2(3)Can the Court set another defence period?
Yes. Rule 2(3) permits the Court to specify a different period.
Rules of the High Court (Cap. 4A), Order 18, rule 2(3)Do acknowledgment expiry and claim service still control this branch?
The ordinary paragraph (1) is displaced by the qualifying paragraph (3) determination.
Rules of the High Court (Cap. 4A), Order 18, rule 2(3)Is Summer Vacation still omitted?
Yes, unless the Court otherwise directs. This remains a High Court pleading-service period governed by Order 3 rule 3.
