Cross-Appeals and Their Own Timing
A party who was perfectly content with a decision until the other side appealed it has a window of their own in which to challenge it, and that window is usually short, is counted differently, and is missed with some regularity.

The rule in short
Where one party appeals, another may wish to challenge parts of the decision that went against them. That cross-appeal has its own deadline, frequently measured from service of the first notice rather than from the decision, and frequently shorter. Failing to file one leaves a respondent able to defend the decision but not to improve upon it.
An appeal changes the position for everybody, including the party who had decided not to appeal. Their own window opens when the notice arrives and it is usually shorter than the one they let pass.
What a cross-appeal is for
Challenging parts of a decision. Where a respondent lost on some issues and accepted that outcome until the other side appealed the rest.
Seeking a better outcome. A respondent without a cross-appeal can usually defend the decision and not improve on it.
Preserving alternative reasoning. Some systems allow a respondent to support a decision on different grounds without cross-appealing, and some do not.
Raising a conditional challenge. Where a point only matters if the appellant succeeds, which is the classic cross-appeal.
Responding to a partial appeal. Where the appellant narrowed the scope and the respondent wants other parts examined.
Balancing the risk. An appeal that could only go one way becomes a matter where both sides have something at stake.
Affecting settlement. Which is frequently the practical reason one is filed.
Not for defending as decided. A respondent content with the outcome does not need one to argue the decision was right.
Not a second chance generally. The scope of a cross-appeal is limited to the decision already under appeal.
Not available against a non-appellant. A cross-appeal responds to the appeal that was brought, and challenging a party who has not appealed is a separate exercise.
The timing
It has its own deadline. Separate from the appellant's, and running on its own basis.
Usually counted from the first notice. Service of the appellant's notice is commonly the trigger rather than the decision itself.
Frequently shorter. A period of a couple of weeks is typical where the original period was longer.
Sometimes counted from the decision too. Where the respondent could have appealed independently, both periods may be relevant.
Additional time may apply. Where the notice was served by post, per deemed receipt, explained plainly.
It runs while advice is taken. Which is why the decision has to be made quickly rather than considered at leisure.
Extension may be available. Subject to the same analysis as any appeal period, per extending the appeal period.
The trigger should be recorded. As with every appeal deadline, alongside the date it produces.
Diarize it on receipt. The day the appellant's notice arrives, before anything else is done with it.
| Party | Deadline runs from | Effect of missing it |
|---|---|---|
| Appellant | The decision | No appeal |
| Cross-appellant | The first notice | Defend only |
| Additional respondent | Service on them | Same |
| Late cross-appeal | Relief needed | Uncertain |
| No cross-appeal | — | Decision stands |
Deciding whether to file one
Identify what was lost. Which parts of the decision went against the respondent and whether any of them matter.
Consider whether it changes the outcome. A cross-appeal on a point that alters nothing is not worth the cost.
Consider the cost. It expands the appeal and the work on both sides.
Consider the risk. A cross-appeal exposes the respondent to an adverse costs order on that part.
Consider the leverage. It changes the settlement position, which is frequently the real reason.
Consider whether it is necessary. Some arguments can be run without one, and the rules on that vary.
Take advice quickly. Because the period is short and runs from service of the appellant's notice.
Decide deliberately. Rather than allowing the deadline to answer the question by expiring.
Record the decision. Including the reasons for it, because the client may well ask about it later.
Consider a conditional cross-appeal. Where a point only matters if the appellant succeeds, saying so frames the challenge accurately and limits the exposure.
The appellant's notice does two things: it starts an appeal and it opens a short window for everybody else. The second is easy to overlook because the document is about somebody else's case.
Filing it
Use the prescribed form. Which may be a notice of cross-appeal or a respondent's notice depending on the system.
Identify the parts challenged. Precisely, since scope operates the same way as on an original appeal.
State the grounds where required. Some systems require them at this stage rather than later.
Serve everybody. The appellant and any other party affected, per one document, two recipients.
Pay any fee. Cross-appeals frequently attract their own charge.
File within the period. Which is short, and which nobody will remind anybody about.
Keep the proof. Filing receipt and proof of service, as with any appeal document.
Diarize the consequential steps. Grounds, the record and any bundle, which move quickly.
Tell the client what changed. The matter has become a two-way appeal with an entirely different risk profile.
Reassess the costs estimate. A cross-appeal expands the work on both sides, and the budget agreed for defending an appeal no longer describes what is happening.
What happens without one
The decision stands as made. So far as the respondent is concerned, whatever the appeal outcome.
Defense remains available. A respondent can argue the decision was correct on the reasoning given.
Improvement generally does not. The appellate body cannot usually give the respondent more than they already had.
Alternative grounds may or may not be open. Which varies between systems and should be checked rather than assumed.
The risk becomes one-sided. The appellant can only gain and the respondent can only lose, which affects settlement.
A late cross-appeal is possible sometimes. Subject to the usual analysis about relief, per a late notice of appeal.
Findings become fixed. Anything unchallenged by either side is settled for the purposes of the appeal.
It cannot be raised at the hearing. A point not properly before the appellate body is generally not open.
The decision is usually deliberate. Or it should be, rather than a deadline that nobody happened to notice.
Settlement discussions change. A one-sided appeal produces very different negotiations from a two-sided one, and that difference is frequently the whole point.
A respondent who wants to challenge parts of a decision has to file a cross-appeal, and it carries its own deadline separate from the appellant's.
That deadline is usually counted from service of the first notice rather than from the decision, and it is frequently shorter than the original appeal period.
The decision whether to file one has to be made quickly, weighing what was lost, whether it changes the outcome, the additional cost and the effect on settlement.
Without a cross-appeal a respondent can generally defend the decision as made but cannot improve on it, which leaves the risk in the appeal entirely one-sided.
The practical step is to diarize the cross-appeal deadline the day the appellant's notice arrives, because nothing else in the process will draw attention to it.
Points to carry away
- A cross-appeal has its own deadline.
- It is usually counted from the first notice.
- It is frequently shorter than the original period.
- Without one, a respondent can defend but not improve.
- The decision has to be made quickly.
Questions readers ask
When does a cross-appeal deadline run from?
Usually from service of the appellant's notice of appeal rather than from the decision itself, and the period is frequently shorter than the original appeal window. That means a respondent who had decided not to appeal suddenly has a short and separate deadline, triggered by a document about somebody else's case. Diarizing it the day the notice arrives is the only reliable way to catch it.
What can a respondent do without filing a cross-appeal?
Defend the decision as it stands. A respondent without a cross-appeal can generally argue that the decision was correct on the reasoning given, and in some systems can support it on alternative grounds, though that varies and should be checked. What they usually cannot do is obtain a better outcome than the decision already gave them, which leaves the risk in the appeal entirely one-sided.
Is a cross-appeal worth filing?
It depends on what was lost and whether any of it changes the outcome, but the effect on the balance of risk is frequently the real consideration. An appeal in which only one party can gain looks very different from one in which both have something at stake, and that difference shows up in settlement discussions. The cost and the exposure to an adverse costs order on the cross-appealed points weigh the other way.

More in The Window to Appeal
The Event That Opens the Appeal Window
Appeal windows run from a trigger defined by the applicable rule: the pronouncement of a decision, its entry, its service, or occasionally its receipt. Different systems and different decision types use different triggers, and the difference is frequently decisive because appeal periods are short and rarely extendable. Establishing the trigger is the first step in calculating anything.
Appealing Part of a Decision
An appellant can usually challenge part of a decision rather than the whole of it, and the notice defines that scope. A narrow scope reduces cost and focuses the argument, and it also forecloses points that turn out to matter. Because widening the scope after the period has expired is difficult, the definition deserves more thought than it usually receives.
Appealing Once the Window Has Closed
Where an appeal period has expired, the first question is whether any relief exists. Many appeal windows are absolute. Where relief is available, it depends on how quickly the applicant moved, why the period was missed, whether the respondent has relied on finality, and whether the appeal has merit. The notice should be filed alongside the application.
