942 LOUISIANA LAW REVIEW [Vol. 76
a. Historic Civil Law Roots
The Anglo-American common law did not originate the theory of
promissory estoppel, as a form of the doctrine had already existed for
centuries in the civil law.
146
The two civilian theories are the Roman
principle venire contra factum proprium—no one is allowed to go against
the consequences of his own act—and the German doctrine of culpa in
contrahendo—fault in contracting.
147
Louisiana courts have acknowledged and applied these two theories.
148
For example, one court has held on the basis of venire contra factum
proprium non valet
“that our lessor cannot be allowed to evict our lessee
for failing to actually spend the withheld rent on repairs when it was the
lessor herself who importuned the lessee to delay those repairs.”
149
Thus,
detrimental reliance is a well-established civilian concept that has taken
146. As explained by Shael Herman:
Anglo-American jurisprudence did not invent detrimental reliance as a
substitute for consideration or a basis for enforcement. On the continent,
it already had long and venerable antecedents before the Norman
Conquest. It appeared in Roman texts, and so venerable was the idea of
detrimental reliance that it even acquired its own Latin maxim: venire
contra proprium factum (no one can contradict his own act).

UL. L. REV. 707, 714 (1984); see also
Snyder, supra note 144, at 712 n.100.
147. Adcock, supra note 141, at 755–56. For a more in-depth discussion of the
two theories see Mattar, supra note 138, and Bains v. Young Men’s Christian
Ass’n of Greater New Orleans, 969 So. 2d 646, 649 (La. Ct. App. 4th 2007).
Venire contra factum proprium is sometimes referred to as the longer venire
contra factum proprium non valet. Compare Tex. E. Transmission Corp. v.
Amerada Hess Corp., No. CIV. A. 97–0518, 1997 WL 613125, at *11 (E.D. La.
1997), with Sanders v. United Distributors, Inc., 405 So. 2d 536, 537 (La. Ct. App.
1981).
148. See Coleman v. Bossier City, 305 So. 2d 444, 447 (La. 1974) (discussing
culpa in contrahendo but holding under the circumstances there was no need to
decide whether or not the theory would be applicable); Hebert v. McGuire, 447
So. 2d 64, 65 (La. Ct. App. 1984) (“If the promise had come after the debt for
surgery was incurred, it would be a clearer case of a gratuitous promise, as to
which estoppel (or the civil law doctrine against contravening one’s own acts)
would, however, reasonably apply . . . .” (emphasis in original)); Saúl Litvinoff,
Still Another Look at Cause, 48 L
A. L. REV. 3, 22 (1987) (“[T]he Louisiana
jurisprudence, in a clear manner, has traced the ancestry of reliance as basis for
obligation back to the civilian venire contra factum proprium.”); but see Sanders,
405 So. 2d at 537 n.2 (“This writer has not found an instance of Louisiana’s
expressly utilizing the civil law principle venire contra factum proprium non
valet.”).
149. Davilla v. Jones, 418 So. 2d 724, 725 (La. Ct. App. 1982). But this decision
was later overruled by the Louisiana Supreme Court with no mention of the
doctrine. Davilla v. Jones, 436 So. 2d 507 (La. 1983).
