The use of experts in the review of tax cases is recognized globally. Nigeria appears to appreciate the importance of this practice. However, several previous attempts to establish tax courts or tribunals have been frustrated due to a lack of constitutional support. In the search for a better model for Nigeria, this article examines the US and Canadian experiences of using specialized tax courts or tribunals to see what lessons Nigeria could learn. The two north American experiments justify the use of tax courts as better alternatives to what Nigeria currently has. In particular, the Canadian experience appears to be more suited to the Nigerian context. Therefore, it is argued that Nigeria's 1999 Constitution should be amended to establish a Tax Court of Nigeria, which should be recognized as a superior court of record.
