Finality
See also Appeals (reopening) & Collective redress notes (opt-out / binding opt-in)
The value of certainty
Ampthill Peerage Case (1977) per Lord Wilberforce
the need for justice, including certainty & finality, can prevail over need for truth
if rights can always be unwound, then are less valuable & creates uncertainty
Exceptions
Appeals, including out of time
Judgments to be attacked on grounds of fraud (at least of a party, if not of witnesses)
Extensions of limitation periods for mistake, fraud etc
Interests
Certainty of rights — favours finality, unless claim based on rights frustrated by factors beyond claimant’s control
Access to justice
Proportionate use of public & private resources — proportionality can cut both ways, so fact sensitive
For defendants, peace from litigation & vexation
Public interest in correct outcomes — but time erodes value of evidence
Avoiding inconsistent judgments
Rules for avoiding re-litigation
Time limits
Res judicata
Same parties cannot relitigate same issue — including (a) cause of action estoppel and (b) issue estoppel
Arises only in relation to final judgments — include default & consent judgments
Possibly only adversarial litigation — eg child welfare proceedings excluded
Can be waived — subject to public interest in overriding objective re fair allocation of resources
Applies only to same parties or their privies: Resolution Chemicals
Whether new party had interest in subject matter of previous litigation
Whether new party was in reality the party to the original proceeding
Whether it was just that the new party should be bound by the outcome of the previous litigation
Policy
Protects due process rights of strangers
Judgments inadmissible as evidence in other proceedings: Bairstow
Where one party is the same — eg should defendant to several actions on same issue be bound / permitted to relitigate losses or be able to invoke wins against strangers —
But parties invest resources in litigation based on value of dispute — not based on prospective claims
<> uses court resources, risk of inconsistent judgments
Taylor v Nugent — claimant outside group litigation bound by findings
—Cause of action estoppel
Once cause has been adjudicated, estopped from asserting or denying the cause in subsequent proceedings
Even if new argument, new evidence, or change in the law
Was considered to be an absolute bar — until Virgin Atlantic (claimant ordered to pay damages for infringement of patent — patent later revoked by EUPO with retrospective effect on grounds of prior use CA: damages still due for cause of action estoppel — SC: damages could be overturned)
Dilutes difference with issue estoppel
Consequence of concurrent jurisdictions
If had happened between two English proceedings?
Sumption — validity of patent was decided, but consequences of revocation by EUPO hadn’t been decided
But clearly, because EUPO was not in issue — would mean that any subsequent change in law could reopen
Neuberger — effect of revocation is retrospective so people are entitled to conduct themselves as though it never existed
—Issue estoppel
Parties are bound by findings in subsequent proceedings for separate cause of action between them—
If findings essential to final resolution to those proceedings
Based in proportionality analysis — if issue wasn’t necessary to resolution for dispute, may not have been fully argued & best evidence presented — so needn’t bar reargument
If issues are alternatives and only one succeeds, then may not be blocked by issue estoppel
Unless there are ‘special circumstances’, including if —
Fresh evidence could not have been obtained without reasonable diligence
There has been a material change in the law
Abuse of process — enlarged res judicata
Applies if—
issue has not been decided but could & should have been decided in earlier proceeding; or
Issue has been decided in earlier proceedings involving different parties if it would be unjust to allow relitigation
Used to
Prevent collateral attacks on court judgments:
Hunter (IRA bombing — criminal prosecution — argued confessions extracted by confession — rejected at trial — then brought civil claims collateral attack on criminal convictions — even though no identity of parties, would be abuse of process)
Would it be manifestly unfair to allow matters to be relitigated; or would it bring administration of justice into disrepute: Bairstow (company director lost unfair dismissal claim as guilty of grave misconduct — in regulatory action against him contested the issue on facts as well not abusive)
Avoid multiplicity of actions: Henderson v Henderson
Lord Bingham in Barrow — requires parties to bring their whole case before the courts rather than reserving issues for later
Principles derived by Clarke LJ in Dexter (Claimant company sued director for misappropriation of funds & got judgment — then sued second director as well — second director argued abuse of process not abuse of process)
Aldi Stores (defective building work — other claimants sued builders & consultants together — Aldi got judgment against builders & sought to use judgment to recover full amount from builders’ insurers — pursued consultants — consultants said abuse of process as should have been joined Jackson J struck out — CA overturned — Aldi were open about position and did not use underhanded tactics)
Thomas LJ — legal system must provide parties freedom in how to prosecute claim, and allow claimants to vindicate rights — effectively, taxpayer should fund litigation — contrary to overriding objective?
No risk of inconsistent judgments because first matter was settled — but if Aldi first sued party with least resources to defend litigation and then pursued another party
