English — Original Teaching Answer
Fraud and the available remedies
Mary knowingly lied about Sam's parentage to induce Wanda to transfer property. Wanda reasonably relied and gave her $150,000 and shares then worth $50,000. The false statement was material, and the resulting loss supports fraud. Wanda may undo the fraudulently induced gifts and seek restitution. A completed gift does not become immune from rescission simply because no price was paid, and Wanda received nothing she must return.
A constructive trust restores identifiable property wrongfully obtained or retained when Wanda has the superior equitable entitlement. It follows traceable substitutes and their appreciation. An equitable lien instead secures repayment against specific property. Mary's lack of sufficient assets makes an ordinary damages award potentially inadequate. Although a constructive trust is a remedy rather than an independent tort, the underlying fraud supports the pleaded relief. The court should not dismiss adequately alleged tracing claims merely because Mary changed the property's form.
1. The autographed baseball
Mary's account contained Wanda's $150,000 and Mary's $500 when she paid $1,000 for the baseball. Combining those funds does not prevent tracing. Under the ordinary presumption that a wrongdoer uses her own money first, $500 of the purchase was Mary's and $500 was Wanda's. Wanda can therefore seek a one-half beneficial interest in the baseball, including corresponding appreciation, or a $500 equitable lien. An indivisible object can be sold and its proceeds allocated; physical indivisibility is not a complete defense.
Wanda can alternatively argue that the entire purchase should be attributed to her money, with Mary's original $500 assigned to later dissipated withdrawals. Tracing presumptions protect the victim and should not enable a conscious wrongdoer to preserve investments while allocating losses to the victim. The final allocation depends on the accepted tracing method and evidence, but at least the $500 contribution is established.
Sam gave no value for the baseball. He is an innocent donee, not a protected purchaser for value. Neither innocence nor minority destroys Wanda's proprietary interest in an asset still in his hands. The claim concerning the baseball survives the motion, although Sam is not thereby personally responsible for Mary's fraud.
2. The condominium
The $100,000 down payment came from the same mixed account. Mary's original $500 was either exhausted in buying the baseball or may be allocated to other dissipated withdrawals. The remaining acquisition contribution is therefore traceable to Wanda.
Wanda should seek ownership subject to Bank's mortgage rather than assume that her recovery is necessarily limited to one-quarter of the property's value. Where all nonborrowed purchase money is the claimant's, financing the balance does not itself give the wrongdoer a beneficial ownership share. Wanda can claim the entire equity while leaving the secured debt intact. If the mortgage remains $300,000, the $450,000 condominium has $150,000 net equity, including $50,000 appreciation. Evidence of Mary's own additional acquisition funds could require a proportional allocation instead.
Alternatively, Wanda can request a lien for her $100,000 contribution, ordinarily with interest, but that remedy does not confer the property's appreciation. Bank gave value, and there is no indication it knew of Mary's fraud. Its mortgage therefore remains superior. Wanda cannot take the condominium free of Bank's security. The motion should be denied as to the traceable equity.
3. The stock and prepaid tuition
Before the sale, rescission would permit recovery of the 1,000 shares. After sale, Wanda's proprietary claim followed them into the $100,000 proceeds. A conscious wrongdoer must restore attributable gains, not merely the shares' initial $50,000 value.
Mary no longer possesses the stock or sale proceeds. A good-faith buyer who paid value without notice would take the shares free of Wanda's claim. An innocent school receiving tuition in exchange for educational services generally has a purchaser-for-value defense; the school is also not presently a defendant.
Education already consumed is not an identifiable asset that can be returned. However, payment for four future years may leave refund rights or unconsumed contractual benefits belonging to Mary or Sam. Wanda should investigate those possible substitutes rather than assume all value disappeared when payment occurred. Refundability is not established. Without a surviving traceable benefit, proprietary relief concerning the proceeds fails, but Mary remains personally liable to restore the $100,000 gain. Sam's restitution exposure depends on benefits still retained and any applicable innocent-recipient defense, not simply on being Mary's child.
4. The bank balance and delay
The remaining $35,000 is traceable to Wanda's deposit. No intervening deposit or lower balance is shown, so the entire amount is available for a constructive trust or lien. A demonstrated lower intermediate balance could restrict tracing, and Wanda cannot assume that unrelated later deposits automatically restore previously dissipated money. All recoveries must be coordinated to avoid collecting the same loss twice.
Mary will argue that Wanda knew of the lie in December but waited until June. The holidays explain only a short delay. Nevertheless, delay alone is insufficient: laches requires unreasonable delay and resulting prejudice, and delayed rescission notice defeats relief only if substantially prejudicial. The baseball and condominium purchases preceded Wanda's discovery, so they were not undertaken in reliance on her silence; appreciation alone is not prejudice.
The February tuition payment is Mary's strongest prejudice argument, particularly if irreversible. Wanda can answer that Mary always knew of her own fraud, no reliance on Wanda's silence is established, and prepaid benefits may remain recoverable. A conscious wrongdoer also cannot ordinarily invoke the good-faith change-of-position protection. The complaint can communicate Wanda's election to rescind. Thus, disputed delay does not justify wholesale dismissal; even if some equitable relief ultimately fails, an otherwise timely fraud-damages claim remains available.

中文参考译文
欺诈与可获得的救济
Mary明知Sam的父亲不是Wanda已故丈夫，却为促使Wanda转移财产而作相反表示。Wanda合理信赖，交付十五万美元及当时价值五万美元的股票。亲子关系属于重要事实，财产损失支持欺诈请求。Wanda可以撤销受欺诈诱导的赠与并请求返还。赠与已经完成、受赠人没有支付价款，都不意味着赠与不能因欺诈而撤销；Wanda也没有收到需要返还的对待利益。
当特定财产被不当取得或保留，且Wanda拥有优先的衡平权益时，可以通过拟制信托取回该财产。该救济可以追及可追溯的替代财产及其增值。衡平留置权则在特定财产上担保返还债务。Mary资产不足，使普通金钱判决可能不能提供充分救济。拟制信托虽然是救济方式而非独立侵权，但基础欺诈行为足以支持所请求的救济。不能仅因Mary改变财产形式，就驳回已充分提出的追溯请求。
1. 签名棒球
Mary花一千美元购买棒球时，账户中混有Wanda的十五万美元和Mary自己的五百美元。混同本身不妨碍追溯。按照通常推定不法行为人先花自己钱款的分析方法，其中五百美元属于Mary，另五百美元来自Wanda。因此，Wanda可以请求棒球的一半受益权益及相应增值，或者在棒球上设立担保五百美元的衡平留置权。不可物理分割的物品可以出售后分配价款，物品不可分本身不是完全抗辩。
Wanda也可以主张将整个棒球购买归属于自己的钱款，把Mary原有的五百美元分配到后来被耗散的支出。追溯推定旨在保护受害人，不能让明知实施不法行为者保存投资收益，却将损失全部归给受害人。最终分配取决于法院接受的追溯方法与证据，但至少五百美元的出资已经可以确认。
Sam没有为棒球支付对价。Sam是无辜受赠人，而非受到保护的有偿购买人。无辜和未成年都不会消灭Wanda在其仍持有的财产上的权益。因此，棒球请求应当保留，不过，这不等于Sam须为Mary的欺诈承担个人责任。
2. 公寓
十万美元首付款来自同一混同账户。Mary原有的五百美元，要么已经在购买棒球时花完，要么可以分配给其他已耗散的支出。剩余购房出资因此可以追溯至Wanda。
Wanda应请求取得受银行抵押权约束的所有权，不能直接假定自己只能拿到房产价值的四分之一。如果全部非借贷购房款都来自权利人，借款支付其余价款，本身不会使不法行为人取得一份受益所有权。Wanda可以主张全部净权益，但担保债务仍然保留。如果贷款余额仍为三十万美元，现值四十五万美元的公寓净权益为十五万美元，其中包含五万美元增值。若有证据证明Mary另投入了自己的购房资金，则可能需要按比例分配。
另一条救济路径是在公寓上为Wanda十万美元出资设立留置权，通常可以附带利息，但不使她取得房产增值。银行提供了对价，题目没有显示其知道欺诈，因此其抵押权保持优先。Wanda不能取得不受该抵押权约束的公寓。对可追溯净权益提出的请求不应被驳回。
3. 股票与预付学费
股票出售前，撤销赠与可使Wanda取回一千股股票。出售后，其财产性请求追及十万美元售股所得。明知实施不法行为者应返还可归属的收益，而不仅是股票最初五万美元的价值。
Mary已经不持有股票或售股款。善意、不知情并支付对价的股票买受人可以不受Wanda请求影响。无辜学校因提供教育服务而收取学费，通常也有有偿受让人的抗辩；而且学校目前并不是被告。
已经消费的教育服务不是可以取回的特定财产。不过，预付未来四年学费可能留下Mary或Sam享有的退款请求权，或尚未消费的合同利益。Wanda应调查这些替代利益，而不能认定付款时全部价值就必然消失。题目没有说明是否允许退款。如果没有尚存且可追溯的利益，针对售股款的财产性救济无法实现，但Mary仍须承担返还十万美元收益的个人债务。Sam是否负返还责任，取决于仍保留哪些利益及是否适用无辜受领人的抗辩，而不是只因Sam是Mary的孩子。
4. 银行余额与迟延
剩余三万五千美元可以追溯至Wanda原来的存款。题目没有显示账户其间降至更低余额或后来另有存入，因此全部余额可以成为拟制信托或留置权的对象。如果证明中间曾出现更低余额，追溯范围可能受限；Wanda也不能直接假定无关的后来存款自动补足已耗散的钱款。各项赔偿与返还必须相互协调，避免同一损失获得双重清偿。
Mary会主张Wanda十二月已经知道谎言，却一直等到六月才起诉，节日只能解释短暂拖延。不过，仅有迟延并不够：迟延抗辩需要不合理拖延及其造成的不利影响；迟延通知撤销也只有在实质损害另一方时，才使相关救济落空。棒球与公寓在Wanda发现欺诈之前已经购入，不能说这些支出是因信赖她沉默而作；财产升值本身也不是不利影响。
二月支付学费是Mary最有力的不利影响论证，尤其是在不能撤回付款时。Wanda可以回应：Mary始终知道自己的欺诈，题目没有证明其依赖Wanda沉默作出支出，预付利益也可能仍能追回。明知实施不法行为者通常不能援引善意改变处境的保护。起诉状本身可以表达Wanda撤销的选择。因此，对迟延的争议不支持全部驳回；即便部分衡平救济最终不成立，在其他条件满足且未过时效时，欺诈损害赔偿请求仍可继续。
