Powers and responsibilities
In all four
Kentucky constitutions, the first power enumerated to the governor is to serve as
commander-in-chief of the state's
militia and military forces.
 In 1799, a stipulation was added that the governor would not personally lead troops on the battlefield unless advised to do so by a resolution of the
 Such a case occurred in 1813 when Governor
Isaac Shelby, a veteran of the
Revolutionary War, was asked to lead a band of Kentucky troops to aid
William Henry Harrison at the
Battle of the Thames.
 For his service, Shelby received the
Thanks of Congress and the
Congressional Gold Medal.
Among the other powers and responsibilities of the governor that appear in all four constitutions are the power to enforce all laws, the power to fill vacancies in elected offices until the next meeting of the General Assembly, and the power to remit fines and grant
 The power to pardon is not applicable to cases of
impeachment, and in cases of
treason, a gubernatorial pardon is only effective until the end of the next session of the General Assembly, which can grant a full pardon for treason.
 The 1891 constitution further required that, with each application for a pardon, the governor file "a statement of the reasons for his decision thereon, which ... shall always be open to public inspection."
 This requirement was first proposed by a delegate to the 1850 constitutional convention, but it was rejected at that time.
 Historically, power in Kentucky's executive has been split amongst a variety of elected positions—including
Auditor of Public Accounts,
Treasurer, and several commissioners—but in the late 20th century, political power has centralized in the office of Governor.
Convening and adjourning the legislature
The power of the governor to adjourn the General Assembly for a period of up to four months if the
two houses cannot agree on a time to adjourn appears in all four constitutions.
 The governor is also empowered to convene the General Assembly "on extraordinary occasions".
 Since the 1799 constitution, the governor has been permitted to call the legislature into session somewhere other than the
state capital if the capital had, since the last legislative session, "become dangerous from an enemy or from contagious diseases."
 This was an important provision in the early days of the Commonwealth, when
smallpox posed a danger to the populace.
 One notable example of an attempt to employ this power was in 1900 when
William S. Taylor attempted to adjourn the legislature and re-convene it in heavily Republican
London, Kentucky following the shooting of
 Taylor claimed a state of insurrection existed in the capital, but defiant
Democrats refused to heed the call to adjourn or to convene in London.
The 1891 constitution added a provision that the governor must specify the reason for any specially-called legislative session, and that no other business could be considered during the session.
 There is, however, no constitutional requirement that the legislature conduct any business during the called session. In 2007, Republican governor
Ernie Fletcher called the Assembly into session to consider a long list of items.
 The Democratically-controlled
House of Representatives maintained that none of the items were urgent enough that they could not wait until the regular session convened; they claimed that Fletcher was calling the session only to boost his sagging poll numbers before the
upcoming election in which he faced a challenge from Democrat
 The House convened on the day appointed and adjourned an hour later without transacting any business.
The 1799 constitution contained, for the first time, the power of the governor to
veto legislation; this power was substantially similar to, and probably based upon, that found in the 1792
New Hampshire Constitution and the 1798
 The governor's veto can be overridden by a majority vote of both houses of the legislature.
 The 1891 constitution empowered the governor with a
line-item veto, but its use was forbidden on constitutional amendments and laws related to the classification of property for tax purposes.
U.S. President, the governor does not have the option of a
pocket veto. If the governor does not make a decision to sign or veto a bill, it automatically becomes law after ten days.
 In the event that the legislature adjourns to prevent the return of a bill by veto, the bill becomes law three days after the commencement of the next legislative session unless the governor explicitly vetoes it.
 (With the federal pocket veto, the bill is considered vetoed after ten days if the legislature adjourns.)
Although setting the state budget is a legislative function in many states, Kentucky governors are required by statute to present a proposed biennial budget to the General Assembly for approval shortly after the beginning of its even-year sessions.
 The governor's budget has often been approved with few changes, but since the Republicans took control of the
state senate for the first time in 1999, approval has become a much more contentious process.
 The General Assembly failed to pass a budget before the end of its session in both 2002 and 2004.
 In both cases, the state operated under an executive spending plan drafted by the governor until the legislature could re-convene and pass a budget.
 In 2005 the
Kentucky Supreme Court ruled that the governor had no authority to expend funds without legislative approval, and that if legislators failed to pass a budget in the future, only expenditures explicitly authorized in the state constitution could be made.
Administration and appointments
Although the Kentucky constitution designates the governor as the head of the executive branch of state government, it does not specify the means of carrying out that role.
 Empowered to nominate all constitutional officers by the state's first constitution, that power of the office of the governor has been reduced in subsequent constitutions, as more of those offices became elective.
 Because the governor is not explicitly authorized by the constitution to conduct many of the functions necessary to administer the state government, the officeholder has had to rely on empowering legislation enacted by the General Assembly.
 With this in mind, Kentucky historian
Thomas D. Clark wrote in 2004 that extensive executive powers had been granted through the creation of a large number of commissions that reported to the governor:
During the past century and a half, and especially in the later 20th century, it would have been impossible for state government to operate efficiently without a broadening of executive powers. Through the years the General Assembly has created a myriad of commissions and turned them over to the governor to exercise administrative oversight. ... All of these commissions extended the influence of the governor into every phase of human life in the commonwealth, well beyond the limitations of executive power envisioned by delegates to the constitutional convention in 1891.
By 1934, the executive branch consisted of sixty-nine boards, commissions, and agencies in addition to the constitutional officers, although the members of these commissions were often the constitutional officers themselves. Governor
Ruby Laffoon proposed the Administrative Reorganization Act of 1934 to organize these boards and commissions into seventeen executive departments and seven independent agencies. The General Assembly passed this legislation, giving the executive branch some semblance of structure for the first time.
Happy Chandler created greater efficiency in state government under the Reorganization Act of 1936.
A. B. "Happy" Chandler, called a special legislative session in 1936 seeking passage of another reorganization act.
 This act abolished several commissions and organized those remaining into ten statutory departments: Finance, Revenue, Highways, Health, Welfare, Industrial Relations, Business Regulation, Conservation, Libraries and Archives, and Mines and Minerals.
 The Act also created the Executive Cabinet, consisting of the constitutional officers and the heads of each of the ten statutory departments.
 The efficiencies created by Chandler's reorganization allowed him to pay off more than three-quarters of the state's $28.5 million debt.
 Besides effecting the reorganization of the executive branch, the Reorganization Act of 1936 also explicitly empowered the governor to appoint executive department heads and establish, combine, or divide departments as necessary.
 Later statutes gave the governor the power to appoint advisory committees on reorganization, appoint deputy heads of divisions, transfer employees and change their responsibilities within the executive branch, and establish general rules of conduct for executive branch members.
In the 35 years between the time of Chandler's reorganization and the election of
Wendell H. Ford as governor in 1971, the executive branch had again become unwieldy. 60 departments and 210 boards reported directly to the governor by 1972, and duplication of services between departments had created inefficiencies. On January 1, 1973, a plan that Ford had issued in late 1972 took effect, consolidating the departments reporting to him into six program cabinets: Consumer Protection and Regulation, Development, Education and the Arts, Human Resources, Safety and Justice, and Transportation. Ford continued merging departments and reorganizing the executive branch throughout 1973 to the extent that, by the end of the year, there were only three program cabinets (Development, Education and the Arts, and Consumer Protection and Regulation) and four additional departments (Human Resources, Justice, Natural Resources and Environmental Protection, and Transportation).
By 2002, the executive branch had again grown to fourteen cabinets, but had no additional departments.
 Shortly after his election in 2003, Governor Ernie Fletcher undertook the last major reorganization of the executive branch to date, reducing the number of cabinets to nine—Justice and Public Safety, Education and Workforce Development, Environmental and Public Protection, Transportation, Economic Development, Health and Family Services, Finance and Administration, Tourism, Arts and Heritage, and Personnel.
Because the governor controls so many appointments to commissions—approximately 2,000 according to a 1992 estimate—the office has been historically considered one of the most powerful state executive positions in the
 Additionally, the governor is given wide discretion in awarding state contracts, further augmenting his influence.
 In the second half of the 20th century, attempts were made to curb the use of the governor's appointment power for political
patronage. During his second term in office, Happy Chandler issued an executive order creating a
merit system that forbade the hiring or firing of state employees for political reasons; his successor,
Bert T. Combs, pushed a new merit system through the legislature, protecting it from abolition by executive order.
 Despite the presence of the merit system, many governors have been criticized for abusing their appointment power.
 In 2005, Ernie Fletcher and several members of his administration were
indicted for violating the merit system in their hiring practices; the charges were later dropped as part of an agreement with the prosecutor,
In The Kentucky Encyclopedia,
Eastern Kentucky University professor Paul Blanchard writes that "Many observers consider the governor's informal powers—those derived from tradition, custom, and precedent—as important as the formal powers."
 Frequently the leaders of their political parties at the state level, Kentucky governors usually control the party's delegations to state and national party conventions.
 Though given few powers with regard to the legislature, Kentucky governors can exercise a great deal of influence over the General Assembly, often hand-selecting the leadership of both chambers.
 A move toward a more independent legislature began in the last quarter of the 20th century, particularly during the administration of Governor
John Y. Brown, Jr. from 1979 to 1983.
 Brown was much less engaged in legislative affairs than his predecessors; he did not seek to influence the selection of the legislature's leadership, and he left on vacation during one of the two legislative sessions of his term.
 The trend toward a coequal legislature continued under the administrations of Brown's two immediate successors,
Martha Layne Collins and
Wallace Wilkinson, neither of whom was considered a strong executive.
The governor is also the most visible state officer and is the center of political attention in the Commonwealth.
 The official host of the state when dignitaries visit, the governor frequently delivers addresses at various dedications and ceremonies, and appears on national television with the winner of the annual
 The state constitution requires the governor to address the legislature periodically regarding the state of the Commonwealth.
 This address, traditionally given annually, is often targeted directly at the state's citizens as much as, or more so than, the legislature.
 The governor can use the address to extol the accomplishments of his or her term and lay out a specific plan for the upcoming legislative session; the contents of the address often shape the agenda of the session.
 The state's media outlets devote significant coverage to the governor's actions, and many strong governors have used the media to win support for their agendas and criticize political enemies.
