- 7 - Petitioners alternatively argue that the third protocol, i.e., the amendment to the U.S.-Canada Treaty that was signed on August 31, 1994, contains language against double taxation similar to the U.S.-Canada Treaty in effect during 1987. As a later expression of the sovereign will, petitioners argue that the third protocol overrides section 59(a)(2). However, the third protocol has not been ratified by the United States and Canada and is, therefore, not effective. Moreover, the protocol provides generally that, upon the exchange of the instruments of ratification, the protocol will be effective on a prospective basis, rather than retroactively. Accordingly, in petitioners' case, section 59(a)(2) remains the last expression of the sovereign will. Respondent, therefore, is sustained on this issue. Section 6651(a)(1) provides an addition to tax for the failure to file a timely income tax return, unless the failure to timely file is due to reasonable cause and not due to willful neglect. Section 6653(a)(1) provides an addition to tax if any part of the underpayment of tax is due to negligence or intentional disregard of rules or regulations. Negligence has been defined as a lack of due care or the failure to do what a reasonable and ordinarily prudent person would do under the circumstances. Marcello v.
