consensus in idem Flashcards
What is “consensus in idem”?
“Consensus in idem” means a meeting of minds between parties on the essential terms of the contract.
What principle was established in Muirhead and Turnbull v Dickson (1905)?
Commercial contracts are based on outward expressions (words or actions), not internal thoughts.
What was the issue in Mathieson Gee Ltd. v Quigley (1952)?
There was a mismatch between the offer (to supply plant) and acceptance (of silt removal service), meaning no true agreement was formed.
What is always considered an essential term of a contract?
The identification of the parties to the contract (e.g., Fleming Buildings Ltd v Forrest [2010] CSIH 8).
What are essential terms in a contract of sale?
The goods or land to be sold must be identified, and there must be agreement that a price is to be paid.
Is an agreed price always essential in a contract of sale?
No, under s.8 of the Sale of Goods Act 1979, the court can fix a reasonable price if none is agreed.
How does the required identification of subject-matter vary in sales?
It depends on the nature of the item: fungible goods (e.g., barrels of sugar) can be identified by class, whereas heritable property (land/buildings) requires detailed identification (Bogie v The Forestry Commission 2002 SCLR 278).
What are essential terms in a lease?
The property to be leased, the rent to be paid, and the lease duration. Other terms like rent review clauses or purchase options may also be essential.
Offer and acceptance analysis:
An offer accepted is a contract, because it is the deed of two, the offeror and the acceptor’ (Stair, Institutions, I.10.6)
What principle was affirmed in Bogie v The Forestry Commission (2002)?
Courts will prefer a construction that treats the parties’ communications as forming a binding contract, if such a reading is available (per Lord MacFadyen, para. 38).
What does Avintair v Ryder Airlines (1994) illustrate?
It supports the courts’ willingness to find binding agreements even when all terms have not been finalised.
What principle is illustrated in RTS Flexible Systems Ltd v Molkerei Alois Muller GmbH (2010)?
A legally binding contract can exist even if not all significant terms are finalised, based on an objective appraisal of the parties’ words and conduct.
What is an offer in contract law?
A statement of terms which the offeror proposes to the offeree as the basis of an agreement (15 Stair Memorial Encyclopedia, para 62).
What case supports the requirement that an offer must contain essential terms?
William Lippe Architects Ltd v Innes [2006] CSOH 182A.
Why must an offer be communicated to the offeree?
Because an offeree cannot accept an offer they are unaware of (Thomson v James (1855)).
What is the rule when an offer is made to a specific person?
Only that particular person can accept it (Fleming Buildings Ltd v Forrest [2010] CSIH 8).
