Shirley Lute and Lynda Branch were each convicted of murdering their abusive husbands. After serving many years in prison, each of them petitioned the Governor for clemency. They were among 45 out of 992 petitioners that were granted clemency by Governor Bob Holden in 2004. *433His commutations eliminated from Lute’s and Branch’s sentences the prohibition against probation or parole. The Missouri Board of Probation and Parole (“Board”) denied parole to Lute and Branch, stating that granting parole would depreciate the seriousness of the present offense. Both women sought writs of habeas corpus from this Court, which were issued, and the cases were briefed and argued. As habeas corpus is an original remedial writ, this Court has jurisdiction. Mo. Const, art. V, sec. 4. This Court issues writs of mandamus ordering the Board to promptly conduct parole hearings for Lute and Branch in accordance with this opinion.
I. Facts Relating to Shirley Lute
At 76-years old, Shirley Lute is the oldest female inmate in the Missouri Department of Corrections and has been in prison 29 years. The following history of Lute’s abuse was alleged in her clemency petition and considered by the Governor.
Shortly after Shirley Lute met Melvin Lute, he began to physically and mentally abuse her. They married in 1976, and throughout their marriage, he would punch her in the ribs and breasts and jaw, kick her in the stomach, and bite her breasts. He instructed her to never tell anyone about the abuse. He would place her in karate holds and bend each of her fingers back to force her to comply with his sexual demands. He frequently put a dog collar on her and made her bark like a dog. During one incident, he tied her to their bed and choked her and burned her with cigarettes. He was a non-smoker and had purchased the cigarettes solely to torture her. He refused to untie her to let her go to the bathroom and she was forced to urinate on herself. On more than one occasion he locked her in an unheated, rodent-infested basement for days without warm clothing, food, or water. During another incident, he threw her out of his moving truck. Then he went back and chased her down, threw her back into the truck, drove to a secluded location and kicked, punched, and choked her.
Melvin Lute was killed on the night of February 6, 1978, by Roy Welch, Shirley Lute’s son.1 She was arrested and charged with the murder in 1978 and has remained in prison ever since. She has always denied her involvement in the murder. At her trial, the prosecutor claimed that she offered her son money from life insurance proceeds if he killed Melvin Lute. Outside of a single comment made by Shirley Lute about a time when Melvin Lute had hit her and kicked her in the leg, no evidence about her abuse was offered at trial. Missouri’s statute permitting the admission of evidence on battered spouse syndrome was not enacted until 1987. She was convicted of first degree murder on June 11, 1981, and sentenced to life in prison without the possibility of parole for 50 years.
On December 28, 2004, Governor Holden commuted Lute’s sentence. The commutation stated:
After examination of the application and facts relevant thereto, and upon recommendation of the Board of Probation and Parole, I hereby grant to Shirley Lute a commutation of the above sentence, in the following respect. This commutation eliminates from the sentence the prohibition against eligibility for parole for 50 years, and makes Shirley Lute eligible for parole consideration.
The Board denied Lute parole.2 Its decision stated the reason for the action tak*434en as: “Release at this time would depreciate the seriousness of the present offense based upon the following: A. Circumstances surrounding the present offense.”
Lute filed this petition for a writ of habeas corpus. At this time, she remains imprisoned at the Chillicothe Correctional Center, where she has been a model prisoner. She asks this Court to order her release so that she may live the remainder of her life with her daughter, son-in-law, and grandchildren in Missouri.
II. Facts Relating ,to Lynda Ruth Branch
Lynda Ruth Branch has been imprisoned for over 20 years. The following history of Branch’s abuse was alleged in her clemency petition and considered by the Governor.
Raymond Branch brutally beat and tortured Branch throughout the course of their 11-year marriage. The abuse began on their wedding night. Branch, seven-months pregnant at the time, was sitting in a rocking chair. Raymond Branch hit her so hard that the chair was knocked over and she landed on her stomach. She miscarried a week later. The abuse continued and got progressively worse throughout the marriage. He cut her with a knife and the top of a can. He shot at her. He beat her with a telephone receiver when she tried to call for help. He threw her down the stairs. He cracked her ribs, pulled her hair out, and blackened her eyes so badly that she temporarily lost her eyesight. Knowing that she was afraid of small spaces, he locked her in closets and made her beg to be let out. He also handcuffed her and burned her with cigarettes. He forced her to crawl across the floor and to perform sex acts. He slept with his leg over her to make sure she did not leave the bed when he was sleeping, and he marked her tires and mileage to ensure that she did not leave the house when he was gone. He killed her cat and tied it to her car’s rearview mirror. The last week of their marriage, he handcuffed her to the kitchen table, ripped off all of her clothes, put a candle in her vagina and lit it, allowing the hot wax to burn her.
Lynda Branch shot Raymond Branch twice the night of May 16, 1986. At trial, she claimed that they had quarreled throughout the day and that Raymond Branch was drinking. She had told him she was leaving him.. After she went to sleep on the couch, he woke her up and ordered her to go to the bedroom “where she belonged.” Later that night, she awoke to him pointing a gun at her that was wrapped in a sheet. She recognized it as a gun because it was from his truck. She claims that he threatened to kill her and her daughter. After that, a struggle ensued and the gun went off. Raymond Branch was shot. Then, when she took the gun out of the sheet, it went off again. The prosecution claimed that she premeditated the killing and then tried to cover it up by moving his body and changing her clothes and the bed sheets.
Branch’s first conviction was reversed because some evidence of the domestic abuse was excluded. See State v. Branch, *435757 S.W.2d 595 (Mo.App.1988). She was convicted again on March 3, 1989, of first degree murder and sentenced to life in prison without the possibility of parole for 50 years. State v. Branch, 811 S.W.2d 11, 11 (Mo.App.1991). For unexplained reasons, her lawyers in the second trial again did not introduce all of the evidence of the abuse.
Branch petitioned the Governor for clemency and on November 24, 2004, Governor Holden commuted her sentence. His commutation stated:
After examination of the application and facts relevant thereto, I hereby grant to Lynda Branch a commutation of the above sentence, in the following respect. This commutation eliminates from the sentence the prohibition against probation or parole and makes Lynda Branch eligible for probation or parole consideration.
The Board denied her parole.3 Its order stated that the reasons taken for the action were: “Release at this time would depreciate the seriousness of the present offense based upon the following: A: Circumstances surrounding the present offense, B: Use of a weapon, C: Use of excessive force or violence.”
Branch petitioned this Court for a writ of habeas corpus. She asks that this Court release her from prison. She would like to spend time with her daughter, her grandchildren, and her elderly mother.
III. Discussion
The issue before this Court is the effect of the Governor’s commutations. Lute and Branch argue that the Board’s denial of parole was contrary to the intent of the Governor’s commutations. The State argues that the commutations are clear upon their face.
The governor is the head of the executive branch. Mo. Const, art. IV, sec. 1. The Missouri Constitution gives the governor the power to commute and pardon criminal convictions. Mo. Const, art. IV, sec. 7. When prisoners petition the governor for clemency, the Board investigates each case and submits a report of its investigation, along with its recommendations, to the governor. Section 217.800, RSMo 2000. The Board must follow the governor’s orders as he is granted the sole authority to commute sentences at his discretion.
In interpreting the Governor’s commutations, this Court must give effect to the Governor’s intent. This is consistent with long-standing precedent holding that the power to grant commutation is “a mere matter of grace” that the governor can exercise “upon such conditions and with such restrictions and limitations as he may think proper.” Ex Parte Reno, 66 Mo. 266, 269, 273 (1877); Ex Parte Webbe, 322 Mo. 859, 30 S.W.2d 612, 615 (banc 1929).
Both of the Governor’s commutations here explicitly stated that he made the decision to commute the sentences to make them eligible for parole “[a]fter an examination of the application and facts relevant thereto.” While the commutations might not have explicitly stated that the Governor had considered “the seriousness of the present offense,” that is neces*436sarily implied because otherwise the Governor would not have recommended these two women for parole after considering the facts of their cases.4
Any doubt regarding the intent of the Governor is resolved by his sworn affidavits.5 In Lute’s case, Governor Holden’s affidavit stated that:
This denial of her parole by the Board was inconsistent with my clear intent as I had already given detailed consideration of the circumstances surrounding her offense.... In reviewing Ms. Lute’s application, I had deemed that her release would not depreciate the seriousness of her offense_ In reviewing Ms. Lute’s application, I considered: the circumstances surrounding her offense, the inadequate defense presented in Ms. Lute’s trial, the lack of knowledge at the time of Battered Women’s Syndrome, the length of time she had spent in prison, her exemplary behavior while incarcerated, her age and health, and the fact that Ms. Lute had served the retributive and deterrent portion of her sentence.
In Branch’s case, Governor Holden’s affidavit stated that:
In coming to the commutation decision, I reviewed the facts of Lynda Branch’s case, including the circumstances surrounding her crime, the abuse she suffered at the hands of her husband, and the fact that she used a weapon to commit her crime.... When determining whether or not Lynda Branch should be released on parole, I did not intend that the Board of Probation and Parole would reexamine the same factors as I did when granting her clemency.
These affidavits make clear that the Governor did not intend for the Board to use the same factors he had considered as bases for denying parole. Even though the Board did not have the benefit of the affidavits in rendering its decision, this Court does now. The affidavits conclusively resolve any ambiguities in the commutations. To ignore the Governor’s expressed intent in this petition for an original remedial writ of habeas corpus would amount to a derogation of the Governor’s constitutional authority to exercise grace under article IV, section 7. Governor Holden made his intent clear as to what the Board should do with respect to Lute and Branch in his affidavits.
With respect to Lute, Governor Holden further attested:
[HJaving determined that Shirley Lute’s release would not depreciate the seriousness of her crime, and given that she also had an exit plan and an exemplary prison record, I believe the Parole Board exceeded its authority when it denied parole for Shirley Lute.
As such, this Court remands Lute to the Department of Corrections and orders the Board to promptly conduct a parole hearing to decide the conditions of her parole, but not to re-consider any of those factors attested to by the Governor in his affidavit.
With respect to Branch, Governor Holden stated in his affidavit that the “job of the Board of Probation and Parole in evaluating Lynda Branch’s eligibility for parole post commutation [is] to examine her conduct in prison and determine her readi*437ness to re-enter society, and not to review the circumstances of her crime or her use of a weapon.” As such, this Court remands custody of Branch to the Department of Corrections and orders the Board to promptly conduct a parole hearing for her in conformity with the Governor’s stated intent in his affidavit with respect to whether she should be paroled.
In sum, the appropriate remedy at this point is not habeas corpus but mandamus.6 This Court accordingly issues writs of mandamus ordering the Board to promptly conduct parole hearings for Lute and Branch in accordance with this opinion.
WOLFF, C.J., STITH, TEITELMAN and WHITE, JJ., concur. PRICE, J., concurs in part and dissents in part in separate opinion filed. LIMBAUGH, J., dissents in separate opinion filed.. Roy Welch pled guilty to second-degree murder and received 30 years.
. The Board did not hold a parole hearing until over five months later, on June 2, 2005, *434and did not render its decision until August 2, 2005. The Board’s regulations state that "[t]he parole board will reach a decision within ten (10) working days from the date of the hearing, or as soon as practicable, and the inmate will receive a written notice of the board’s action as soon as the notice can be prepared and delivered.” 14 CSR 80-2.010(8)(A). The Board’s decision did not provide an explanation for its delay beyond the time set in its regulations, nor is any explanation offered why it was not practicable to issue its one-sentence order in a more timely fashion. By the time of the hearing, Governor Holden was no longer in office.
. The Board did not give Branch a parole hearing until over six months later, on June 1, 2005, and it did not render its decision until a month later. As in the case of Lute, it is unclear why the parole board did not give Branch a hearing until over six months after the commutation order. It is also unclear why the Board’s decision was not made until a month later. Under parole regulations, the decision must be made within 10 working days of the hearing or as soon as practicable. 14 CSR 80-2.010(8)(A).
. The Governor does not have the power himself to parole. Mo. Const, art. IV, sec. 7.
. Governor Holden’s affidavits are appropriate to use to discern the intent of his commutations because he was the sole author and only his intent is relevant. In contrast, for example, affidavits of legislators are not admissible to discern legislative intent because an affidavit from a legislator only reflects the intent of one legislator out of 197 that voted on a particular bill.
. This Court issued writs of habeas corpus on November 21, 2007, which technically resulted in this Court taking custody of both women, though their physical custody remained in the Department of Corrections subject to this Court’s authority. Having determined that a writ of mandamus is the proper remedy in both cases, this Court relinquishes its habeas corpus authority over the custody of the women so that the Board can promptly conduct parole hearings as required by the writs of mandamus.
