in lieu of
From French au lieu de, from the classical Latin expression (in) locō, meaning "in place (of)", consisting of the the ablative of locus (“place”), preceded or followed by a genitive, as in “parentis loco esse”, Cicero, Div. in Caecil., 19.61.

Using to mean “in light of” is etymologically incorrect (it is literally “in place of”), and thus considered an error.
