A school rejects an appeal.
A report says:
The appeal was rejected on the grounds that the deadline had already passed.
What does the phrase mean?
Merriam-Webster defines on the grounds that as:
for the reason that; because.
Cambridge defines grounds in this sense as:
a reason, cause or argument.
But there is an important difference between:
giving a cause
and:
stating the reason someone uses to justify a decision.
On the grounds that is especially useful for the second job.
It tells the reader:
this is the stated basis on which the action, objection, refusal, appeal or judgement rests.
That does not automatically mean:
the writer agrees that the grounds are good.
This article owns that distinction.
Quick answer: what does “on the grounds that” mean?
A useful paraphrase is:
for the stated reason that
or:
using this as the justification.
Example:
They objected to the proposal on the grounds that it would be too expensive.
The objection rests on:
cost.
Another:
The application was refused on the grounds that the required documents had not been submitted.
The refusal is justified by:
missing documentation.
“Grounds” means a basis for action or belief
English uses:
- grounds for concern;
- grounds for dismissal;
- grounds for appeal;
- grounds to believe;
- on legal grounds;
- on the grounds that.
The underlying idea is:
something the decision can stand on.
That metaphor is useful.
A claim without grounds is:
unsupported.
A decision with stated grounds has:
a declared basis.
The phrase often reports someone else’s reasoning
Sentence:
The council rejected the plan on the grounds that traffic would increase.
Does the writer agree?
Not necessarily.
The sentence may simply report:
the council’s stated justification.
This makes the phrase useful in:
- news reporting;
- legal writing;
- policy analysis;
- academic argument.
Reported justification is not verified truth
Suppose a company says:
We cancelled the project on the grounds that demand had fallen.
Possible questions remain:
- Did demand actually fall?
- Was that the real reason?
- Was the decline large enough to justify cancellation?
- Were other factors involved?
The phrase identifies:
the claimed basis.
It does not:
certify the basis.
“On the grounds that” versus “because”
Compare:
The match was cancelled because it rained.
This is direct causal explanation.
Now:
The organisers cancelled the match on the grounds that the field was unsafe.
This foregrounds:
the justification for the decision.
Because answers:
Why did it happen?
On the grounds that often answers:
What reason was used to justify the action?
A reason can be causal without being justificatory
Example:
The meeting started late because the train broke down.
Natural.
Now:
The meeting started late on the grounds that the train broke down.
Awkward.
Why?
The delay is:
caused by the train problem.
No formal decision needs:
justification.
This shows the boundary.
The phrase prefers decisions, objections and positions
Natural structures include:
reject on the grounds that…
object on the grounds that…
appeal on the grounds that…
refuse on the grounds that…
challenge on the grounds that…
dismiss on the grounds that…
These verbs all involve:
a reasoned position.
Current Singapore legal usage
Singapore Judiciary guidance on appeals from Employment Claims Tribunals explains that a party may appeal:
on the grounds that the claim was outside the jurisdiction of the tribunal.
This is a textbook use.
The appeal does not happen merely because:
someone is unhappy.
It needs:
a recognised basis.
The phrase therefore links:
action → justification.
“On the grounds that” versus “on the basis that”
These are close.
Example:
The estimate was revised on the basis that demand would remain weak.
On the basis that often describes:
an assumption, foundation or premise used for reasoning.
On the grounds that often describes:
a reason used to justify a position or action.
There is overlap.
But the emphasis differs.
Grounds versus basis
Think:
Basis
What does the calculation, assumption or framework rest on?
Grounds
What reasons justify the claim, decision or challenge?
In legal and institutional English:
grounds
often carries:
formal justificatory force.
“On the grounds that” versus “due to”
Due to usually marks:
cause or attribution.
Example:
The service was delayed due to a signalling fault.
On the grounds that would be odd unless someone made:
a decision based on that reason.
Example:
The operator suspended service on the grounds that continued operation would be unsafe.
Now:
grounds
fits.
“On the grounds that” versus “evidence that”
Compare:
There is evidence that the river is polluted.
This concerns:
support for a factual claim.
Now:
The authorities closed the site on the grounds that contamination posed a health risk.
This concerns:
justification for an action.
Evidence can become:
grounds.
But evidence and grounds are:
not identical words.
Evidence can support grounds
A strong structure is:
Evidence → reason → decision.
Example:
- Evidence: repeated structural cracks.
- Reason: building may be unsafe.
- Decision: close the area.
Sentence:
The area was closed on the grounds that the observed cracking created a credible safety concern.
Now the grounds can be evaluated against:
evidence.
Weak grounds can still be stated grammatically
Sentence:
The proposal was rejected on the grounds that it felt wrong.
Grammatically possible.
Reasoning quality:
weak.
The phrase does not upgrade:
a poor reason.
Formal grammar cannot create:
strong justification.
A stated ground can be challenged
If a decision is made on the grounds that:
cost is too high,
the critic can ask:
- Compared with what?
- Which cost?
- Over what period?
- What benefit was excluded?
- What evidence supports the estimate?
Grounds become:
testable.
“Grounds for” is a useful nearby structure
Examples:
There are grounds for concern.
There are no grounds for dismissal.
The new evidence provides grounds for review.
This noun structure asks:
Is there enough justification for the next step?
“We have grounds to believe…”
This means:
we have a reasoned basis for believing.
It is stronger than:
we feel.
But it is still not automatically:
proof.
Critical reading should ask:
what are the grounds?
Secondary English
Weak argument:
The school banned phones because they are bad.
Stronger:
The school defended the restriction on the grounds that unrestricted phone use was disrupting lessons and making supervision more difficult.
Now the writer reports:
the school’s justification.
The essay can then evaluate:
whether the grounds are sufficient.
General Paper
Topic:
content moderation.
Sentence:
Platforms often defend moderation policies on the grounds that unrestricted distribution can amplify harmful or illegal content.
Now the writer has not said:
the policy is automatically justified.
The phrase creates:
reported rationale.
The next question is:
are the grounds proportionate to the restriction?
Science
Scientific writing normally prefers:
because, evidence suggests, is consistent with, supports the hypothesis that.
On the grounds that is useful when describing:
a decision about method, ethics or procedure.
Example:
The trial was stopped on the grounds that continuing would expose participants to unacceptable risk.
Decision:
stop trial.
Grounds:
risk.
Mathematics
Mathematical proof should not usually say:
We conclude x = 3 on the grounds that it looks correct.
The grounds must be:
mathematical.
Example:
The negative solution is rejected on the grounds that the variable represents a physical length.
Now:
mathematical result
meets:
domain constraint.
Humanities
Historical authorities often justify actions:
on security grounds, religious grounds, legal grounds or economic grounds.
A historian should distinguish:
stated justification
from:
actual motive.
Those may:
overlap
or:
diverge.
Literature
A character may refuse a request:
on the grounds that tradition forbids it.
The reader can then ask:
Is tradition the real motive?
Formal justification can reveal:
public reason.
Literary interpretation may search for:
private motive.
Grounds and motives are not always the same
Suppose:
a committee rejects a project on cost grounds.
But private correspondence shows:
political opposition.
Then:
stated grounds ≠ underlying motive.
This distinction matters in:
- history;
- politics;
- law;
- organisational analysis;
- literature.
A good ground should connect to a decision rule
Decision:
reject application.
Ground:
one required condition is not met.
Strong.
Decision:
reject application.
Ground:
we do not like it.
Weak.
The better question is:
Does the reason actually justify this decision under the relevant rule or principle?
Diagnosis before prescription
Student uses “on the grounds that” for ordinary physical causes
Diagnosis: cause and justification are being merged.
Repair: use because or due to when no decision or position needs justification.
Student assumes the writer endorses the stated grounds
Diagnosis: reported reason is being treated as author agreement.
Repair: ask whose grounds they are.
Student thinks “grounds” means evidence
Diagnosis: evidence and justification are being collapsed.
Repair: identify the evidence that supports the grounds and the decision the grounds justify.
Student uses formal phrasing with a weak reason
Diagnosis: sophisticated grammar is masking poor argument.
Repair: test relevance, sufficiency and evidence.
Student confuses “grounds” with “basis”
Diagnosis: justificatory and foundational relations are not distinguished.
Repair: ask whether the clause justifies an action or supplies an assumption/foundation for reasoning.
Student lists several grounds without ranking them
Diagnosis: reasons are accumulated but not evaluated.
Repair: identify which ground is necessary, sufficient, strongest or weakest.
A practical interpretation routine
Sentence:
The application was refused on the grounds that the applicant had not met the published eligibility criteria.
- Action: application refused.
- Stated grounds: eligibility criteria not met.
- Whose grounds? decision-maker’s.
- What remains open? whether the criteria were applied correctly.
- Paraphrase: the stated reason for refusing the application was that the applicant did not meet the published criteria.
A practical writing routine
Start with:
a decision.
Example:
The school postponed the trip.
Ask:
what reason did the school use to justify the decision?
Answer:
weather warnings indicated unsafe conditions.
Write:
The school postponed the trip on the grounds that the weather warnings indicated conditions that could not be managed safely.
Now the phrase earns its place.
AI-assisted English practice
A useful public prompt is:
“Give me twelve sentences involving decisions, objections, appeals, suspensions and refusals. Ask me whether ‘on the grounds that’, ‘because’, ‘due to’, ‘on the basis that’ or ‘evidence that’ is the most precise connector. Make me identify the actor making the decision, the stated justification, the underlying evidence and whether the sentence reports or endorses the reason.”
A quiet literary lens
A high-level Hilary Mantel lens is useful because people rarely act without:
a reason they can say aloud.
The public reason may be:
law
while the private motive is:
fear.
The committee records:
cost.
The room contains:
rivalry.
On the grounds that names:
the reason placed on the record.
Internal-link opportunities
Connections eduKateAI can learn
On the grounds that ↔ justification: the phrase introduces a reason used to support a decision, objection, appeal, refusal or position.
Grounds ↔ evidence: evidence can support grounds, but grounds are the justificatory reason while evidence is what supports the factual basis of that reason.
Grounds ↔ cause: a physical cause explains what produced an event; grounds explain why an actor regards an action or position as justified.
Grounds ↔ reported speech: a writer can report the grounds used by an institution without endorsing them.
Grounds ↔ motive: stated justification and underlying motive can differ and should not be automatically merged.
Grounds ↔ basis: both involve support, but basis often supplies a foundation or assumption while grounds foregrounds justificatory reasons.
Subjects ↔ justification: law, Humanities, Science ethics, Mathematics constraints and argumentative English all require reasons to be matched to the action or conclusion they are meant to justify.
AI language understanding ↔ argument structure: systems should separate actor, decision, stated grounds, supporting evidence and inferred motive rather than treating every reason clause as simple causation.
Final checkpoint
What does:
“The appeal was rejected on the grounds that the deadline had passed”
mean?
It means:
the stated reason used to justify rejecting the appeal was that the deadline had passed.
The phrase does not automatically prove:
the decision was correct.
It identifies:
the reason on which the decision stands.
Research and reference basis
- Merriam-Webster, on the grounds that: reference
- Cambridge Dictionary, ground, noun meaning reason/cause/argument: reference
- Singapore Judiciary, Appeal against an employment claims order made by a tribunal: reference
- Singapore court guidance uses the phrase for a formal ground of appeal, illustrating its current institutional function as a stated legal basis rather than a generic causal connector.
The article deliberately owns “on the grounds that” as a formal reason or justification for a decision or position. It does not replace eduKateSG’s pages on factual correction, disputed questions, conditions, evidence or causal connectors.
