Civil Law — Fundamentals
Jurisdiction: the first question every civil suit must answer
Before any court can hear a civil suit, it must have jurisdiction — and CPC Section 9 establishes the default rule worth memorizing precisely:
Section 9: "The Courts shall (subject to the provisions herein
contained) have jurisdiction to try all suits of a civil
nature EXCEPTING suits of which their cognizance is either
expressly or impliedly barred."
Three types of jurisdiction to distinguish:
Pecuniary jurisdiction (Section 15) — based on the suit's
monetary value; a suit must be filed in the court of the
lowest grade competent to try it
Territorial jurisdiction (Sections 16-20) — based on where
the defendant resides, or where the cause of action arose
Subject-matter jurisdiction — some courts are barred from
certain matters by specific statute (e.g., certain matters
exclusively reserved for specialized tribunals)
A suit filed in a court lacking any one of these three jurisdiction types is liable to be dismissed or transferred, regardless of the substantive merit of the claim — this is exactly why jurisdiction is tested as a threshold, first-principles question in judiciary exams: a candidate needs to correctly identify jurisdiction before any analysis of the substantive dispute is even relevant, mirroring how a real civil court must resolve jurisdiction before proceeding to merits.
Res judicata: preventing the same dispute from being re-litigated
Section 11 requires, for res judicata to apply:
1. The matter directly and substantially in issue must be
the SAME as in the former suit
2. The former suit must have been between the SAME parties
(or parties claiming under them)
3. The former court must have been COMPETENT to try the
matter
4. The matter must have been HEARD AND FINALLY DECIDED
(not just raised, but actually adjudicated)
Worked example: A sues B for possession of a property and
loses on the merits after a full trial. A later files a
fresh suit against B for the same property, framing it as
a claim for damages instead of possession, but the underlying
factual dispute (ownership) is identical.
Res judicata analysis: is this the "same matter"? Even
though the RELIEF sought differs (damages vs. possession),
if the underlying issue actually and substantially decided
(ownership) is identical, res judicata can still bar the
second suit — courts look at the substance of what was
actually decided, not just the form of relief requested
The specific reason res judicata questions test genuine application, not definition recall: exam fact patterns often deliberately vary the form of relief or the specific claim framing while keeping the underlying decided issue identical, testing whether a candidate can correctly identify that the SUBSTANCE of the matter (not the surface framing) determines whether res judicata applies — a candidate who mechanically checks "is this the exact same claim" without looking at the substantially decided issue will miss cases where res judicata genuinely applies despite surface-level differences in how the second suit is framed.
Offer and acceptance: the foundational building blocks of contract formation
Section 2(a): Offer (proposal) — "when one person signifies
to another his willingness to do or abstain from doing
anything, with a view to obtaining the assent of that other"
Section 2(b): Acceptance — "when the person to whom the
proposal is made signifies his assent thereto"
Critical distinction: an offer becomes a promise only upon
acceptance (Section 2(b)) — and acceptance must be
ABSOLUTE and UNQUALIFIED (Section 7); a qualified or
conditional "acceptance" is legally a COUNTER-OFFER, not
an acceptance, and extinguishes the original offer
The counter-offer distinction is a genuinely common source of exam errors and real-world confusion alike: if A offers to sell a car for ₹5 lakh, and B responds "I'll buy it for ₹4.5 lakh," B's response is legally a counter-offer, not a qualified acceptance — A's original offer is now extinguished, and A is free to accept, reject, or further negotiate B's counter-offer, but B cannot later claim to "accept" A's original ₹5 lakh offer as if it were still open, since it no longer exists once B's counter-offer was made.
Essential elements of a valid contract: the checklist behind Section 10
Section 10: "All agreements are contracts if they are made by
the free consent of parties competent to contract, for a
lawful consideration and with a lawful object, and are not
hereby expressly declared to be void."
Breaking this into a checklist:
[ ] Offer and acceptance (Sections 2(a), 2(b))
[ ] Free consent (Section 14 — not caused by coercion, undue
influence, fraud, misrepresentation, or mistake)
[ ] Capacity to contract (Section 11 — of the age of majority,
of sound mind, not disqualified by law)
[ ] Lawful consideration (Section 2(d), 23 — something of
value, not forbidden by law)
[ ] Lawful object (Section 23 — the purpose of the agreement
itself must not be illegal or against public policy)
Every valid contract requires ALL of these elements together — missing even one (a minor's agreement lacking capacity, an agreement for an illegal object) renders the agreement void or voidable, not merely "weaker." This checklist approach — systematically verifying each element against a given fact pattern — is the practical method for solving the problem-based questions the Overview tab specifically identifies as the actual judiciary exam format, rather than attempting to recall a general definition and match it loosely to the facts.
