<blockquote>
  <h1>damages <em>pl. n.</em></h1>
  
  <p>A sum of money awarded by a court as compensation for a tort or a breach of contract. Damages are usually a <a href="https://www.oxfordreference.com/view/10.1093/acref/9780198802525.001.0001/acref-9780198802525-e-2351#" rel="nofollow noreferrer">lump-sum award</a> (see also <a href="https://www.oxfordreference.com/view/10.1093/acref/9780198802525.001.0001/acref-9780198802525-e-3122#" rel="nofollow noreferrer">provisional damages</a>). The general principle is that the claimant is entitled to full compensation (<strong><em>restitutio in integrum</em></strong>) for his losses. <strong>Substantial damages</strong> are given when actual damage has been caused, but <strong>nominal damages</strong> may be given for breach of contract and for some torts (such as trespass) in which no damage has been caused, in order to vindicate the claimant’s rights. Damages may be <a href="https://www.oxfordreference.com/view/10.1093/acref/9780198802525.001.0001/acref-9780198802525-e-149#" rel="nofollow noreferrer">aggravated</a> by the circumstances of the wrong. In exceptional cases in tort (but never in contract) <a href="https://www.oxfordreference.com/view/10.1093/acref/9780198802525.001.0001/acref-9780198802525-e-1474#" rel="nofollow noreferrer">exemplary damages</a> may be given to punish the defendant’s wrongdoing. Damages may be classified as unliquidated or liquidated. <strong>Liquidated damages</strong> are a sum fixed in advance by the parties to a contract as the amount to be paid in the event of a breach. They are recoverable provided that the sum fixed was a fair pre-estimate of the likely consequences of a breach, but not if they were imposed as a <a href="https://www.oxfordreference.com/view/10.1093/acref/9780198802525.001.0001/acref-9780198802525-e-2829#" rel="nofollow noreferrer">penalty</a>. <strong>Unliquidated damages</strong> are damages the amount of which is fixed by the court. Damages may also be classified as <a href="https://www.oxfordreference.com/view/10.1093/acref/9780198802525.001.0001/acref-9780198802525-e-1671#" rel="nofollow noreferrer">general and special damages</a>.</p>

<p>I'll cite some uses of 'quantum'. <a href="https://www.amazon.co.uk/Ansons-Law-Contract-Jack-Beatson/dp/0198734786/ref=pd_lpo_sbs_14_t_0?_encoding=UTF8&amp;psc=1&amp;refRID=ZW82SGPZDB8D0GKSVMV4" rel="nofollow noreferrer"><em>Anson's Law of Contract</em> (2016 30 ed)</a> p 432.</p>

<blockquote>
  <p>&nbsp; &nbsp; &nbsp; Where the covenantee has a legitimate interest which it is entitled to protect, the
  restriction must not be longer in point of time, or wider in area, or otherwise be
  more extensive in scope than is necessary to protect that interest. The answer to this
  question in any individual case, however, must necessarily depend upon the interest
  to be protected, the nature of the contract and the relative positions of the contracting
  parties.159<br>
  &nbsp; &nbsp; &nbsp; The <strong>quantum</strong> of the consideration which the covenantor has received in exchange
  for the restraint is relevant to the determination of the reasonableness of the contract.160</p>

<blockquote>
  <p>Gardner has put
  forward the following ((1999) 115 LQR 438, 452) as a possible hypothesis for the remedial
  regime for proprietary estoppel:</p>
  
  <blockquote>
    <p>The approach is
    – to vindicate the plaintiff’s expectations (care being taken to achieve the best match between
    the details of the plaintiff’s expectations and the possible legal responses);<br>
    – to vindicate those expectations in specie if practicable, but otherwise in a monetary
    form; but</p>
    
    <p>– to resort to some other <strong>quantum</strong>, not more generous than the expectation measure, if it is
    impracticable to give relief in the expectation measure; and<br>
    – to resort to some other <strong>quantum</strong>, with no ceiling at the expectation measure, in the presence
    of another factor from a limited range recognised as meriting a departure from expectation
    relief.</p>

<p>p 608. Hoffmann LJ in W<em>illiam
Sindall plc v. Cambridgeshire County Council</em> [1994] 1 WLR 1016.</p>

<blockquote>
  <p>Damages under section 2(2) are therefore damages for the misrepresentation as such.
  What would be the measure of such damages? This court is not directly concerned with
  <strong>quantum</strong>, which would be determined at an inquiry.</p>

<p>pp 727-728. Robert Goff J.</p>

<blockquote>
  <p>In other cases, however, the actual benefit to the defendant may be considerably more than the appropriate or just sum to be awarded to the plaintiff, in which event the value
  of the benefit will not in fact determine the <strong>quantum</strong> of the award. I should add, however,
  that, in a case of prospecting, it would usually be wrong to identify the discovered mineral
  as the benefit.</p>

<p>p. 817. Lord Lloyd in <em>Ruxley Electronics and Construction Ltd v. Forsyth</em>
[1996] AC 344.</p>

<blockquote>
  <p>Mr Forsyth was, I think, lucky
  to have obtained so large an award for his disappointed expectations. But as there was no
  criticism from any quarter as to the <strong>quantum</strong> of the award as distinct from the underlying principle,
  it would not be right for your Lordships to interfere with the judge’s figure.</p>

<h2>Quantum means “how much”</h2>

<p>It’s simply a synonym for amount or quantity.</p>

<p>It can be applied to damages or anything else that gets measured. The quantum of my height is 180cm, the quantum of my weight I’ll keep to myself.</p>
