1.  No county fuel tax ordinance may be repealed or amended or otherwise directly or indirectly modified in such a manner as to impair adversely any outstanding bonds issued under this chapter or other obligations incurred under this chapter, until all obligations for which revenues from such ordinance have been pledged or otherwise made payable from such revenues pursuant to this chapter have been discharged in full, but the board, with the approval of the governing body of each participating city, may at any time dissolve the commission and provide that no further obligations may be incurred thereafter.

2.  The faith of the State of Nevada is hereby pledged that this chapter, NRS 365.180 to 365.200, inclusive, and 365.562, and any law supplemental thereto, including without limitation, provisions for the distribution to any county designated in NRS 373.030, 373.062, 373.065, 373.066 or 373.0663, of the proceeds of the fuel taxes collected thereunder will not be repealed, amended or otherwise directly or indirectly modified in such a manner as to impair adversely any outstanding bonds issued under this chapter or other obligations incurred under this chapter, until all obligations for which any such tax proceeds have been pledged or otherwise made payable from such tax proceeds pursuant to this chapter have been discharged in full, but the State of Nevada may at any time provide by act that no further obligations may be incurred thereafter.
