The employer, Ohio Pacific Express, sought review of an award of a workers’ compensation claim. § 287.Jj.70.1 The Labor and Industrial Relations Commission dismissed the application for review as untimely pursuant to § 287.480. An appeal was taken to the Missouri Court of Appeals, Eastern District. § 287495. This Court granted transfer after opinion. Mo. Const, art. V, § 10; Rule 83.03. The Commission’s order of dismissal is reversed.
A “Temporary or Partial Award” was entered by the administrative law judge finding claimant Richard Abrams was an employee of the Ohio Pacific Express, claimant was injured by an accident arising out of and in the course of his employment, and claimant suffered total disability from participating in the labor market. The only issues left for future determination were whether future medical aid would be required and whether the claimant might be restored to regular work. The award was made on April 5, 1990.
An application for review dated April 25, 1990, was mailed to the Division of Workers’ Compensation. Postage had been placed on the envelope by a postage meter. The date imprinted by the postage meter was April 25, 1990. The application was delivered on April 26, 1990.
The Labor and Industrial Relations Commission dismissed the application because it was filed more than twenty days after the administrative law judge’s award.
In relevant part, § 287.480 provides:
Any notice of appeal, application or other paper required under this law to be filed with the division or commission shall, when mailed to and received by the division or the commission, be deemed to be filed as of the date endorsed by the United States post office on the envelope or container in which such paper is received.
The issue presented on appeal is whether the date made by the postage meter is to be considered “the date endorsed by the United States post office on the envelope.”
*340Congress has authorized the postal service to adopt regulations, as necessary, to accomplish the objectives given by statute. 39 U.S.C. § 401(2) (1988). The regulations pertinent here are found in the Domestic Mail Manual (DMM), which is made part of the Code of Federal Regulations. 39 C.F.R., § 111.1 (1990). The DMM authorizes postal customers to apply for a license to possess and use postage meters'. DMM 144.14 and 144.21. The license is to be revoked if a meter is used unlawfully. DMM 144.231. The date inscribed by the meter is required to be the actual date of deposit of the mail (or the next scheduled collection day). DMM 144.471. Postmarking or cancelling of metered mail is prohibited unless the date is inaccurate. DMM 144.532. Metered mail must be examined by a postal employee for accurate dating. DMM 144.534.
From the above review of the regulations it is apparent that postal authorities license and regulate the use of postage meters and require accurate dating of metered mail. The regulatory scheme provides for routine inspection of the date on metered mail by postal employees to ensure accuracy of the date before that mail is delivered to the addressee. Those who abuse a postage meter license are subject to sanctions.
The claimant discounts the regulations, arguing that this Court should adopt a narrow construction requiring a postmark date by a postal employee after the envelope is delivered to the post office. The primary role of courts in construing statutes is to ascertain the intent of the legislature from the language used in the statute and, if possible, give effect to that intent. Trailiner Corp. v. Director of Revenue, 783 S.W.2d 917, 920 (Mo. banc 1990). In determining legislative intent, statutory words and phrases are taken in their ordinary and usual sense. § 1.090. That meaning is generally derived from the dictionary. Indian Lake Property Owners Ass’n, Inc. v. Director of Revenue, 813 S.W.2d 305, 308 (Mo. banc 1991). There is no room for construction where words are plain and admit to but one meaning. State ex rel. Missouri State Board of Registration for the Healing Arts v. Southworth, 704 S.W.2d 219, 224 (Mo. banc 1986). Where no ambiguity exists, there is no need to resort to rules of construction.
The verb “endorse” is variously defined as:
... [T]o write on the back of ... to sign one’s name as payee ... to register payments and interest ... to inscribe (one’s signature) ... SIGN ... to inscribe (as an official document) with a title, direction, memorandum, or explanation ... to make over to another ... to acknowledge receipt ... obs.: To load upon the back ... to express definite approval or acceptance of ... support or aid explicitly by or as if by signed statement: vouch for: UNDERWRITE ... SYN See APPROVE....
Webster’s Third New International Dictionary, 749 (1966).
From the above it is apparent that “endorsed” has multiple meanings. In the context of § 287.480, it possibly means the date inscribed on the envelope by an employee of the post office. It may also mean any date inscribed on the envelope that is approved and authorized by the United States post office as the date the letter was received by the post office, regardless of who caused the mark to appear on the envelope. Whether “endorsed” means “approved” or some more restrictive term is not readily apparent. Well within the range of legislative intent is a date inscribed on an envelope by a licensed postage meter, which is thereafter examined for accuracy by a postal employee and finally delivered to the addressee. The ambiguity in the statute requires resort to the rules of statutory construction.
The dissent suggests that by resort to strict rules of grammar regarding placement or absence of commas, the Court may resolve all ambiguity. As convenient as that rule of construction may seem, it is not the primary rule of construction, as suggested by the dissent. Courts in this state are reluctant to construe the intent of the legislature based solely on punctuation and grammatical construction. Application of Graham, 239 Mo.App. 1036, 199 *341S.W.2d 68, 75 (1946). See also Missourians to Protect the Initiative Process v. Blunt, 799 S.W.2d 824, 830 (Mo. banc 1990).
Section 287.480 is the initial step in an appeal of an award of a workers’ compensation claim. Statutes that are remedial in nature are to be liberally construed so as to effect their beneficial purpose. State ex rel. LeFevre v. Stubbs, 642 S.W.2d 103, 106 (Mo. banc 1982). From the earliest cases involving workers’ compensation, the right to appeal was recognized as wholly remedial. De May v. Liberty Foundry Co., et al., 327 Mo. 495, 37 S.W.2d 640, 653 (1931). Cases should be heard and decided on their merits. To that end, statutes and rules relating to appeals, being remedial, are to be construed liberally in favor of allowing appeals to proceed. Sherrill v. Wilson, 653 S.W.2d 661, 663 (Mo. banc 1983). The statute here must be construed liberally to permit a disposition of this case on the merits, rather than on technical grounds.
An equally compelling rule of construction requires the Court to presume that the legislature did not intend to enact an absurd law and favors a construction that avoids unjust or unreasonable results. State ex rel. McNary v. Hais, 670 S.W.2d 494, 495 (Mo. banc 1984). If the Court accepts claimant’s interpretation of the statute, situations would arise where two notices might be mailed at the same time, both properly addressed and with proper postage affixed, one by postage stamps and the other by postage meter. Both envelopes would be duly processed and delivered at the same time. Because the postal regulations prohibit postmarking properly dated metered mail, the notice with postage affixed by a postage meter would be ineffective under the narrow construction suggested. Absent unambiguous language to the contrary, such an absurd, unjust and unreasonable result will not be countenanced.
Claimant relies primarily on two cases, Penn Valley Management, Inc. v. Robertson, 724 S.W.2d 661 (Mo.App.1987), and Patterson v. St. Louis Univ. Hosp., 780 S.W.2d 106 (Mo.App.1989). Of the two, only Penn Valley involved metered mail. In Penn Valley the envelope in which the notice of application for review was delivered was dated by a postage meter on September 9, 1985, which was within the time permitted for application for review. However, the envelope was delivered on September 13, 1985, which fell outside the twenty-day statutory limit. The court in Penn Valley noted the “custom and practice” of the post office not to postmark metered mail, but failed to consider the effect of the postal regulations discussed above. 724 S.W.2d at 662.
In Patterson the notice of application for review was sent by Federal Express prior to the expiration of the twenty-day period but delivered after the twenty-day period expired. 780 S.W.2d at 107. Patterson did not involve an envelope sent through the United States mail. Thus, both Penn Valley and Patterson are distinguishable.
More important than these distinctions, however, is a misstatement of the law found in both cases. One of the major premises relied on in Penn Valley was the application of a rule of strict construction to § 287.480. Applying that rule, the court construed “the date endorsed by the” post office to mean only a postmark made after the envelope has been deposited in the mail. 724 S.W.2d at 663. Patterson reiterated that the statute in question was subject to “literal and strict construction.” 780 S.W.2d at 108. Both cases relied on Tabb v. McGinley, 313 S.W.2d 745 (Mo. App.1958), for that statement of the law. That reliance is misplaced.
Tabb involved a construction of § 287.-480 prior to the 1974 amendment. The 1974 amendment allowed for proof of filing notice by the date endorsed by the post office. Prior to 1974 the statute required an application be “made to the Commission within ten days from the date of the award.” § 287.480, RSMo 1949. The Tabb court did not state that the statute was subject to a rule of “literal and strict construction.” Instead, the court concluded that § 287.480, RSMo 1949, was plain and unambiguous and therefore, not subject to *342the normal rule of liberal construction. Tabb, 313 S.W.2d at 748.
An accurate statement of the rule to be applied in construing any ambiguity in § 287.480 is found in Graves v. O.F. Elliott, Inc., 355 Mo. 751, 197 S.W.2d 977 (banc 1946). There a question existed as to whether the contents of a notice of appeal in a workers’ compensation case were sufficient. This Court said:
Since the statute does not say what shall be stated in the notice, surely any language that can reasonably be construed to show that appellant is in good faith attempting to appeal from the final award in the case ought to be held sufficient. ... [A]ll of the provisions of the Compensation Act shall be liberally construed; that substantial compliance shall be sufficient; and that omissions of a technical nature shall not be fatal.
197 S.W.2d at 979 (emphasis added). See also § 287.800.
From what has been said, it is clear that to the extent Penn Valley and Patterson misstate the law by adopting a rule of “strict construction,” they are inconsistent with the prior holdings of this Court. To that extent, they are overruled.
The liberal rule of construction is not inconsistent with the concept stated in some cases that because the time limits of § 287.480 are jurisdictional, “strict compliance” with those time limits is required. See, e.g., Long v. City of Hannibal, 670 S.W.2d 567, 569 (Mo.App.1984). The requirement of strict compliance with the time limits is not a rule of statutory construction. Strict compliance is required only after ambiguities in the statute are resolved.
It has been suggested that by accepting proof of filing based upon the date made by a postage meter under the control of one of the parties, uncertainty as to the actual date of mailing will result because a negligent or deceitful postal employee may not examine the date and ensure that it is correct. That argument assumes that postal meter licensees and postal employees will not comply with the regulations. The argument is contrary to the usual presumption that “[pjublic officials have rightfully and lawfully discharged their official duties until the contrary appears.” Midwest Materials Co. v. Village Dev. Co., 806 S.W.2d 477, 484 (Mo.App.1991), citing Dittmeier v. Missouri Real Estate Comm’n, 316 S.W.2d 1, 5 (Mo. banc 1958). Even if this Court adopts the view that only postmarks made by postal employees are sufficient, that narrow construction would not prevent the backdating of a postmark by a negligent or deceitful postal worker. Here there is no evidence suggesting deceit or neglect occurred, and the presumption noted above is applicable.
The dissent suggests that a person with a postage meter may use the prior day’s date if the letter is deposited before the first collection of the day. That is not entirely accurate. The regulations clearly require that the date inscribed on the letter must be the date mailed or, if deposited after the last daily collection, the next scheduled collection date. It is possible that an unscrupulous person could place a notice in a mail depository sometime after midnight and the post office would accept the prior day’s date when it makes its first collection the next morning. At most, the unscrupulous person would gain a few hours advantage over those who have no access to postage meters. The alternative is to punish the great number who use postage meters by saying the date on the envelope, though accurate in all respects and accepted as accurate and approved by postal authorities, may not be considered in determining if a document was mailed on time. On balance, the disadvantage of a few hours to those not having access to postage meters is small. At worst, a few workers’ compensation cases will be decided on their merits rather on a procedural default. That disadvantage is hardly the stuff of which the French Revolution was made.
Our holding is consistent with the holding of courts in other states. In a factually similar case, the Supreme Court of Ohio reversed the dismissal of an appeal where notice of appeal was dated by a postage meter on the final day allowable, but it was *343received by the review board three days later. Bowman v. Ohio Bureau of Employment Services, 30 Ohio St.3d 87, 507 N.E.2d 342, 342-43 (1987). The relevant statute allowed mailed notice so long as it was “postmarked” before the appeal period was ended. 507 N.E.2d at 343. Relying on regulations of the Domestic Mail Manual, the court found that “private meter postmarks are ‘postmarks’, presumptively valid and accurate, for purposes of timely filing of an appeal to the board under the Code.” 507 N.E.2d at 344r-45. The highest courts of Iowa and West Virginia have reached the same conclusion on similar statutes requiring a “postmark” within the prescribed period. Severs v. Abrahamson, 255 Ia. 979, 124 N.W.2d 150 (1963); Haynes v. Heckler, 392 S.E.2d 697 (W.Va.1990).
The underlying order of the administrative law judge was designated a “Temporary or Partial Award.” Only a “final award” is appealable. § 287.495. The only statutory mention of temporary and partial awards is found in § 287.510. Substantial caselaw holds that no statutory authority exists for judicial review of temporary or partial awards made pursuant to § 287.510 and its statutory predecessors. State ex rel. Faris v. Eversole, 332 S.W.2d 879 (Mo. banc 1960); State ex rel. Prescott Laundry Co. v. Mo. Workers’ Compensation Comm’n, 320 Mo. 1156, 10 S.W.2d 916 (banc 1928); Boatner v. Slusher, Inc., 614 S.W.2d 35 (Mo.App.1981); Melvin v. Harrison Engineering & Construction Co., 232 Mo.App. 382, 107 S.W.2d 836 (1937); and State ex rel. New Amsterdam Casualty Co. v. Richardson, 227 Mo.App. 1221, 61 S.W.2d 409 (1933). However, more recent authority holds that an award of permanent total disability requiring payments for the remainder of the claimant’s lifetime pursuant to § 287.200.2 is a final award for purposes of appeal under § 287.495 even though designated as a temporary or partial award. Smith v. Ozark Lead Co., 741 S.W.2d 802, 808-810 (Mo.App.1987). While not a model of clarity, the award here seems to be an award pursuant to § 287.-200.2 and not an award pursuant to § 287.-510. Based on Smith, this Court concludes there is jurisdiction of this appeal although the order appealed from is designated a temporary or partial award. The use of an award form entitled “Temporary or Partial Award” may have resulted in confusion and contributed to the employer’s delay in filing the application for review. It would seem to be preferable for the Division of Workers’ Compensation to develop a new form that would not have the misleading effect of implying that the award is not final.
For all the reasons above cited, this Court concludes that a date inscribed on an envelope by a licensed postage meter and delivered to the addressee by the United States post office is the date “endorsed by the United States post office on the envelope.” In this case that date was within the twenty-day requirement of § 287.480. The order dismissing the application for review is reversed and the cause is ordered remanded to the Labor and Industrial Relations Commission for further proceedings consistent with this opinion.
