Why Withdrawal Rights?
HORST EIDENMOLLER*
Abstract: Almost every legal system accepts the fundamental principle that promises must be
kept ('pacta sunt servanda'). Yet, a consumer's right to withdraw from a contract for the
purchase of goods or services ('withdrawal right') figures prominently in European consumer
law directives, in the ACQP and in the DCFR. Withdrawal rights imply a significant weak-
ening of the fundamental principle pacta sunt servanda. However, the popular invocation of
withdrawal rights is not rooted in a thorough analysis of the purposes such rights might fulfill.
This article attempts to provide such an analysis by posing the central normative question:
'Why Withdrawal Rights?'. It uses the tools of (behavioral) economics to identify three situa-
tional categories in which granting a withdrawal right may be justified: information asym-
metries at the time of contract formation, exogenous distortions of the consumer's preferences
and endogenous distortions. The article also seeks to assess the effectiveness of withdrawal
rights in achieving their stated objectives. It contains specific policy recommendations with
respect to the mode in which withdrawal rights should be granted, if they are granted at all
(i.e. mandatory versus optional, etc.).
Resum: La force obligatoire du contrat figure parmi les principes fondamentaux de presque
tons les ordres juridiques. Pourtant, les droits de retractation sont un des instruments essentiels
des directives europeennes concernant la protection des consommateurs, et ils ont aussi un role
important dans les Principes acquis (ACQP) ainsi que dans le projet de Cadre commun de
reference (PCCR). De tels droits impliquent une atteinte signifiante du principe fondamental
'pacta sunt servanda'. La popularit des droits de retractation ne se fonde pas sur une analyse a
fond des objectifs que de tels droits pourraient poursuivre. Cet article entreprend de presenter
une telle analyse en posant la question normative fondamentale: 'Pourquoi des droits de
retractation?'. En appliquant des conceptions de l'&conomie comportementale, trois situations
sont identifiees dans lesquelles un droit de retractation pourrait etre justifie: Une asymetrie
d'information lors de la conclusion d'un contrat, des perturbations des preferences exogenes
du consommateur et des perturbations des preferences endogenes. L'article vise aussi a appre-
cier l'efficacite des droits de retractation quant a l'accomplissement de leurs buts. Il contient
des propositions specifiques concernant le mode dans lequel un droit de retractation, s'il y a
lieu, devrait etre accord (par droit imperatif, en forme d'option etc.).
Kurzfassung: In nahezu allen Rechtsordnungen gehort es zu den grundlegenden Prinzipien,
dass Vertrage eingehalten werden missen. Gleichzeitig sind Widerrufsrechte fur Verbraucher
