Following the Oklahoma Supreme Court ruling the tax increases found in SB845 unconstitutional, Governor Mary Fallin issued Executive Order 2017-29, later amended by subsequent order, to convene a special meeting of the Oklahoma Legislature. Pursuant to Section 7 of Article VI of the Oklahoma Constitution, the Governor recommended the Legislature adopt the following matters:

• Address the budget shortfall associated with the loss of revenue from the unconstitutionality of SB845
• Increase pay for public teachers
• Increase pay for public employees
• Provide supplemental funding for the Oklahoma State Department of Health

Following her veto of the amended fiscal year 2018 Oklahoma state budget, Governor Mary Fallin issued Executive Order 2017-43,[1] later amended by subsequent order[2] and again by an additional subsequent order,[3] to convene a special meeting of the Oklahoma Legislature. Pursuant to Section 7 of Article VI of the Oklahoma Constitution, the Governor recommended the Legislature:

• Provided supplemental funding for the Oklahoma Health Care Authority
• Adopt wide-ranging tax increases and elimination of tax deductions and credits
• Authorize expanded gambling by Native American tribes
• Grant the Governor greater appointment powers over Executive agencies
• Increase pay for public teachers

• On August 10, 2017, the Oklahoma Supreme Court, in the case of Naifeh v. Oklahoma ex rel Oklahoma Tax Commission, ruled 7-2 that SB845 violated the Oklahoma Constitution's tax raising clause by failing to obtain the super-majority of votes in the Legislature needed to raise taxes. SB845 had sought to raise the tax on cigarettes in an attempt to balance the fiscal year 2018 Oklahoma state budget. The Legislature had classified the measure as a "fee" as opposed to a "tax" but the Court disagreed with such classified. Without the revenues from the bill, the state budget lost over $200 million in anticipated revenue, forcing Governor Mary Fallin to convene an extraordinary session of the Legislature to revise the budget.
• On August 31, 2017, the Oklahoma Supreme Court, in the case of Oklahoma Automobile Dealers Association v. Oklahoma ex rel Oklahoma Tax Commission, ruled 5-4 that HB2433 did not violate the Oklahoma Constitution's tax raising clause. HB2433 eliminated an exemption under the current state sales tax code which excluded motor vehicle purchases from the tax. By removing the exemption, the Legislature did not raise a tax for the purposes of the Constitution's tax raising clause and therefore was not required to obtain the super-majority of votes in the Legislature needed to raise taxes.
• On December 19, 2017, the Oklahoma Supreme Court, in the case of Hunsucher v. Fallin, ruled 5-4 that SB643 unconstitutional under the Oklahoma Constitution's single-subject clause and Due Process Clause. SB643 eliminated Oklahoma's administrative hearings procedures for revocation of drivers licenses and allowed the Oklahoma Department of Public Safety to revoke the license without granting the affected driver a hearing before the Department or an administrative opportunity to object.
