OPINION
Thе question presented in this case is whether a statutory amendment to Minn. Stat. § 253B.19, subd. 2(d), effective on August 1, 2010, applies to appellant Ben Braylock’s November 2008 petition for provisional or full discharge from civil commitment as a sexually dangerous offender. Braylock argues that retroactive application of the amended stаtute to his petition is improper because the amendment introduced a new, higher burden for a petitioner seeking provisional or full discharge than the version of the statute that was operative when he filed his petition. The court of appeals affirmed the Supreme Court Judicial Appeal Panel’s decision to deny Braylock’s petition. We affirm the court of appeals.
I.
Appellant Ben Braylock is an 80-year-old, civilly committed, Level-3 sex offender. Braylock was convicted of burglary in 1968, second-degree murder in 1981, third-degree criminal sexual conduct in 1988, and first-degree criminal sexual conduct in 1991. In 2005, the Minnesota Department of Corrections, through the Hennepin County Attorney, petitioned the Hennepin County District Court to involuntarily commit Braylock as a sexually psychopathic personality (“SPP”) and a sexually dangerous person (“SDP”), as defined by Minn.Stat. § 253B.02, subds. 18b-18c (2010). See Minn.Stat. § 253B.185 (2010) (permitting the indeterminate civil commitment of persons classified as SPPs or SDPs). The district court granted the petition and ordered Braylock indeterminately committed as a SDP. In November 2008, Braylock petitioned the Special Review Board (“Review Board”) for a provisional or full discharge from his civil commitment. Minn.Stat. § 253B.18, subd. 4(c)
By statute, a person committed under Minn.Stat. § 25BB.185 who seeks full or provisional discharge must first petition the Review Board for relief. Minn.Stat. § 25BB.185, subd. 9; see also Minn.Stat. § 253B.18, subds. 7, 15 (2010) (describing the showing that a petitioner must make in order to receive a full or provisional discharge and the factors that the Review Board must consider in determining whether to recommend such relief). If the Review Board recommends denial of the discharge petition, then the committed person may petition the Supreme Court Judicial Appeal Panel (“Appeal Panel”) for rehearing and reconsideration of the Review Board’s recommendаtion. See Minn. Stat. § 253B.19, subd. 2(b) (2010); see also Minn.Stat. § 253B.185, subds. 12, 18 (declaring that a discharge petition may not be granted unless the Appeal Panel is satisfied, after a hearing and recommendation by the Review Board, that discharge is appropriate). In proceedings before the Appeal Panel, the committed person “bears the burden of going forward with the evidencе.” Minn.Stat. § 253B.19, subd. 2(d) (2010). If the committed person meets his burden, then the party opposing the petition “bears the burden of proof by clear and convincing evidence that the discharge or provisional discharge should be denied.” Id.
In this case, the Review Board concluded that Braylock failed to satisfy the requirements for full or provisional dischаrge and recommended that the Appeal Panel deny Braylock’s petition. Braylock then petitioned the Appeal Panel for rehearing and reconsideration of the Review Board’s recommendation. Following an April 30, 2010, evidentiary hearing, the Appeal Panel issued its decision on August 6, 2010. The Appeal Panel conсluded that Braylock failed to present sufficient evidence to meet his initial burden of production under Minn.Stat. § 253B.19, subd. 2(d). Based on that conclusion, the Appeal Panel denied Braylock’s petition.
While Braylock’s petition was pending before the Appeal Panel, the Legislature amended Minn.Stat. § 253B.19, subd. 2(d). Prior to August 1, 2010, the relevant portion of subdivisiоn 2(d) stated as follows:
The petitioning party bears the burden of going forward with the evidence. The party opposing discharge bears the burden of proof by clear and convincing evidence that the respondent is in need of commitment.
Minn.Stat. § 253B.19, subd. 2(d) (2008). In May 2010, the Legislature amended that portion of subdivision 2(d) in the following manner:
The petitioning party seeking discharge or provisional discharge bears the burden of going forward with the evidence, which means presenting a prima facie case with competent evidence to show that the person is entitled to the requested relief. If the petitioning party has met this burden, the party opposing discharge or provisional discharge bears the burden of proof by clear and convincing evidence that the respondent, is ■in-need of commitment discharge or provisional discharge should be denied.
Act of May 10, 2010, ch. 300, § 27, 2010 Minn. Laws 747, 764. Because the Legislature failed to sрecify a different date, the amendment became effective on August 1, 2010. See Minn.Stat. § 645.02 (2010).
In March 2011, the court of appeals affirmed the Appeal Panel’s decision. Braylock v. Jesson, No. A10-1754,
II.
In determining which version of Minn.Stat. § 253B.19, subd. 2(d), applies to Braylock’s petition, the threshold question is whether the Legislature’s amendment of subdivision 2(d) was merely a clarification of preexisting law or whether the amendment substantively changed the law. When the Legislature merely clarifies preexisting law, the amended statute applies to all future or pending litigation. See Nardini v. Nardini,
The Legislature’s amendment of a statute creates a presumption that the Legislature intended to change the law. Auto Owners Ins. Co. v. Perry,
Here, the language of the pre-amendment and post-amendment versions of MinmStat. § 253B.19, subd. 2(d), demonstrates that the Legislature intended only to clarify preexisting law. Prior to the
The petitioning party seeking discharge or provisional discharge bears the burden of going forward with the evidence, which means presenting a prima facie case with competent evidence to show that the person is entitled to the requested relief.
Minn.Stat. § 253B.19, subd. 2(d) (2010). A comparison of the twо versions reveals that the amendment did not eliminate the petitioning party’s “burden of going forward with the evidence.” Instead, the Legislature simply appended an additional clause onto the pre-2010 version: “which means presenting a prima facie case with competent evidence to show that the [petitioner] is entitled tо the requested relief.” See Act of May 10, 2010, ch. 300, § 27, 2010 Minn. Laws 747, 764. The phrase introducing the additional clause — “which means” — indicates that the Legislature amended subdivision 2(d) to remove any uncertainty about what is required for petitioners to meet their initial burden of “going forward with the evidence.” Stated differently, the Legislature used the phrase “which means” to desсribe the function of the additional clause, which is to describe or define what the immediately antecedent clause (“bears the burden of going forward with the evidence”) conveys. See Webster’s Third New International Dictionary of the English Language Unabridged 1398 (2002) (defining the word “mean” as “to serve or intend to convey, show, or indicate”); see also id. at 592 (defining “define” as “to discover and set forth the meaning of (as a word or term)” (emphasis added)).
Moreover, the specific language used to amend the statute confirms our conclusion that the amendment was merely definitional or descriptive rather than a substantive change to preexisting law. In fact, the operative language of the amendment — “presenting a prima facie case” — is simply a synonym for a requirement to gо “forward with the evidence.” See, e.g., Castaneda v. Partida,
Braylock nonetheless argues that the requirement of a “prima facie case” changes preexisting law by requiring petitioners to produce a greater quantum or quality of evidence in order to obtain relief. More specifically, Braylock seems to argue that the requirement for a “prima facie case” in amended subdivision 2(d) shifts the burden of persuasion from the party opposing the petition to the petitioning party. We disagree.
Braylock’s argument confuses the “burden of production” in subdivision 2(d) with a burden of persuasion. The burden of production is the obligation of a party tо come forward with sufficient evidence to support its claim or the relief requested. See Bryan A. Garner, Gamer’s Dictionary of Legal Usage 124 (3d ed.2011); see also Aguilar v. Atl. Richfield Co.,
Here, we are convinced that the pre-amendment and post-amendment versions of subdivision 2(d) require the petitioner to meet only a burden of production. In both versions of the statute, the ultimate burden of persuasion remains at all times with the party opposing the petition to prove, by clear and convincing evidence, that a full or provisional discharge should be denied.
III.
For the foregoing reasons, we hold that the court of appeals properly evaluated Braylock’s petition under the amended version of MinmStat. § 253B.19, subd. 2(d). Accordingly, we affirm the decision of the court of аppeals.
Affirmed.
Notes
. Braylock argues that, regardless of the appropriate legal standard, he has provided sufficient evidence to avoid an involuntary dismissal. See Minn. R. Civ. P. 41.02(b). Because we denied review of the merits of Braylock’s petition, we need not and do not express an opinion on the sufficiency of the evidence presented to the Appeal Panel. See Milner v. Fanners Ins. Exch.,
. We acknowledge that the term "prima facie case” is a legal term of art that does not always carry the same meaning in every context. Rather, the specific quantum and quality of evidence that is necessary to establish a prima facie case may vary depending on the naturе of the proceedings, the type of action involved, and the stage of the litigation.
