Etruscan Development Corporation CC was placed in liquidation. Its liquidator, Venter N O, sold 60 immovable properties situated in Sandton. Transfer could not be registered without municipal clearance certificates under s 50 of the Local Government Ordinance 17 of 1939 (Transvaal). The Eastern Metropolitan Substructure demanded payment of R353 616.74 for outstanding assessment rates, interest, rezoning fees, water and sewerage charges, and sundries before issuing the certificates. The liquidator paid the amount to secure transfer but later claimed that a portion (R131 311.72) was not lawfully payable and sought repayment, contending that these amounts were not “taxes” under s 89 of the Insolvency Act and were merely concurrent claims.
