A Batch is an auction subgroup of the Advertised List that serves as a means of organizing tax certificates for the purpose of facilitating bid submission. Each tax certificate in each Batch is auctioned independently of every other tax certificate and arranged in sequential order with a unique auction closing time for each Batch. In each batch, the properties are listed in the order they are listed in the advertisement which is the order they appear on the tax roll. This order cannot be changed.
