This Act codifies Delaware’s longstanding common law recognition of the authority of Delaware counties and municipalities to separately tax different classes of real property if the classification is reasonable and, under § 1 of Article VIII of the Delaware Constitution, the tax rates are uniform for all real property in each classification. See Green v. Sussex County, 668 A.2d 770, 776 (Del. Super. Ct. 1995), aff’d 667 A.2d 1319 TABLE (Del. 1995); Aetna Cas. & Sur. Co. v. Smith, 131 A.2d 168, 177-78 (Del. 1957); Phila. B & W R. Co. v. Mayor & Council of Wilm., 57 A.2d 759, 765-66 (Del. Ch. 1948); Conrad v. State, 16 A.2d 121, 125-26 (Del. 1940). As this Act is a codification of longstanding authority of taxing authorities to separately tax different classes of real property, Section 5 of this Act makes clear that this Act applies to county tax rates retroactively and prospectively.
