v. Idaho Dep’t of Water Res., 138 Idaho 831, 845, 70 P.3d 669, 683 (2003) (citing Willig v. Idaho Dep’t of Health & Welfare, 127 Idaho 259, 899 P.2d 969 (1995)). More specifically, we have held that “[q]uasi-estoppel is properly invoked against a person asserting a claim inconsistent with a position previously taken by that person with knowledge of the facts and his or her rights, to the detriment of the person seeking application of the doctrine.” The Highlands, Inc. v. Hosac, 130 Idaho 67, 70, 936 P.2d 1309, 1312 (1997) (citing KTVB, Inc. v. Boise City, 94 Idaho 279, 282, 486 P.2d 992, 995 (1971)). Usually, a party’s failure to cite any authority for its position would result in the issue being waived. State v. Zichko, 129 Idaho 259, 263, 923 P.2d 966, 970 (1996) (citations omitted) (<HOLDING>). But in this case, we take the opportunity to
holding an argument waived for failure to cite authority holding that issues not supported by propositions of law authority or argument  are waived if either authority or argument is lacking not just if both are lacking holding cases are not authority for propositions not considered holding this court does not consider issues not supported by propositions of law authority or argument holding that issues raised but not supported by argument are deemed abandoned
