ORIGINAL PROCEEDING IN PROHIBITION
This is an original proceeding in prohibition. Relator Kemp, under the Uniform Mandatory Disposition of Detainers Law, §§ 222.080-.150, RSMo 1978, 1 seeks to prohibit the respondent circuit judge from proceeding to try him on a two count information charging him with first degree murder and robbery. Relator alleges the court has lost subject matter jurisdiction by operation of law under § 222.100, for failure to try him within 180 days of receipt of his request for disposition under the Uniform Mandatory Disposition of Detainers Law.
The facts of this case are not contestеd. Relator is presently serving a twenty-nine year sentence in the Missouri state penitentiary. On February 15, 1979, while relator was imprisoned, a two count complaint was filed against relator in Franklin County for alleged offenses committed prior to his imprisonment and a detainer filed with the Division of Corrections. 2 Pursuant to § 222.080, relator requested final disposition of indictments, informations, or complaints pending against him. The request was admittedly received by the Franklin County Associate Circuit Court where the charge was pending and by thе Franklin County Prosecuting Attorney on August 20, 1979. A preliminary hearing was held on February 14, 1980 and the relator was bound over for trial. On March 3, 1980, an information was filed. After several continuances and other procedural delays (all of which occurred after more than 180 days had elapsed from the date of relator’s request), the cause was set for trial on October 7, 1980, at which time relator moved to dismiss for failure to bring him to trial within 180 days from receipt of the request. Judge Hodge overruled the motion on November 14, 1980. Thereаfter this court issued its preliminary writ prohibiting Judge Hodge from proceeding with the trial.
The Uniform Mandatory Disposition of Detainers Law (UMDDL) provides for the prompt disposition of detainers based on untried state charges pending against a prisoner held within this state’s correctional system. It was first adopted in Missouri in 1959, 1959 Mo.Laws H.B. 259, and was amended in 1971 to include complaints as *355 well as untried indictments and informa-tions. 1971 Mo.Laws 277. Eight jurisdictions have adopted the uniform act: Alabama, Arizona, Colorado, Kansas, Minnesota, Missouri, North Dakоta, and Utah. 3 The Missouri version differs from the uniform law by giving the state 180 days to bring the prisoner to trial once a request for disposition of the charge has been made rather than 90 days. This 180 day period may be extended by the court if it is reasonable or necessary, or if the parties stipulate for a continuance. Section 222.100. The purpose of the UMDDL is to provide a relatively simple procedure for an expeditious release of detainers filed against a prisoner. Because of the time limits, it requires the prosecuting officials to move forward to trial of the charge underlying the detainer. It looks toward valid charges being ripened into trials, and invalid charges being dismissed.
Missouri, along with almost all other jurisdictions, also has entered into the “Agreement on Detainers,” §§ 222.160-.220, adopted at the same session of the legislature as the 1971 amendment to the UMDDL. The “Agreement on Detainers” applies to criminal charges pending against a prisoner in another jurisdiction’s correctional system.
Experienсe has shown that once a charge or detainer is filed against an inmate, that inmate’s status within the prison changes adversely. Much has been written about the baleful effect of detainers. In
Smith v. Hooey,
“It is in their effect upon the prisoner and our attempts to rehabilitate him that detainers are most corrosive. The strain of having to serve a sentence with the uncertain prospect of being taken into the custody of another stаte at the conclusion interferes with the prisoner’s ability to take maximum advantage of his institutional opportunities. His anxiety and depression may leave him with little inclination toward self-improvement.”
Id.
at 379,
“The inmate who has a detainer against him is filled with anxiety and apprehension and frequently does not respond to a training program. He often must be kept in close custody, which bars him from treatment suсh as trustyships, moderations of custody and opportunity for transfer to farms and work camps. In many jurisdictions he is not eligible for parole, there is little hope for his release after an optimum period of training and treatment, when he is ready to return to society with an excellent possibility that he will not offend again. Instead, he often becomes embittered with continued institutionalzation and the objective of the correctional system is defeated.”
Dauber, Reforming the Detainer System: A Case Study, 7 Crim.L.Bull. 669, 671 (1971) (quoting Counсil of State Governments, Handbook on Interstate Crime Control 86 (rev. ed. 1949)). See also Wexler and Hershey, Criminal Detainers in a Nutshell, 7 Crim.L.Bull. 753 (1971); Note, Detainers and the Correctional Process, 1966 Wash.U. L.Q. 417.
To allow rehabilitation programs and treatment programs to be planned and carried out, it is necessary that untried charges be disposed of either by trial or by dismissal within a reasonable time. “It is apparent that the aim of the legislature was to prevent those charged with enforcement of criminal statutes from holding over the hеad of a prisoner undisposed of charges against him.”
State v. Wilson,
In ascertaining the uniform and consistent purpose оf the legislature, it is proper to consider acts passed at the same session of the legislature.
State ex rel. Jackson County v. Spradling,
The pertinent statutes are § 222.080.1:
Any person imprisoned in a correctional institution of this state may request a final disposition of any untried indictment, information or complaint pending in this state against him while so imprisoned. The request shall be in writing addressed to the court in which the indictment, information or complaint is pending and to the рrosecuting attorney charged with the duty of prosecuting it, and shall set forth the place of imprisonment. (Emphasis added.)
and § 222.100:
Within one hundred and eighty days after the receipt of the request and certificate by the court and the prosecuting attorney or within such additional necessary or reasonable time as the court for good cause shown in open court, the prisoner or his counsel being present, may grant, the indictment, information or complaint shall be brought to trial; provided, that the parties may stipulate for a continuance or that it may be granted on notice to the attorney of record of an opportunity for him to be heard. If, after such request, it is not brought to trial within the period, no court of this state shall any longer have jurisdiction thereof, nor shall the untried indictment, information or complaint be of any further force or effect; and the court shall issue an order dismissing the same with prejudice. (Emphasis added.)
The procedures to be followed are clearly set out. The inmatе must request final disposition of the pending information, indictment, or complaint. This relator did on August 8, 1979. Copies of the request must be forwarded to the prosecuting attorney and the court in which the untried indictment, information, or complaint is pending. The prosecuting attorney and the Franklin County Circuit Court received the request on August 29, 1979. This started the 180 days during which period (ending February 16, 1980) the relator must have been brought to trial or the court would lose jurisdiction and the cause must be dis *357 missed with prejudice. While the statute provides that “the indiсtment, information or complaint shall be brought to trial” within one hundred and eighty days after receipt of the request, the state argues that the state complied with the statute by “disposing of” the complaint by the preliminary hearing, held February 14, 1980, and that upon filing of the information on March 3, 1980 the state had another one hundred and eighty days in which to try relator.
The state relies on dicta in
State v. Turley,
In Brooks, the complaint charging first degree robbery was filed June 25, 1963. The detainer was filed with the warden July 5, 1963. Relator’s request for disposition under the UMDDL was made July 25, 1969. More than 180 days later, relator moved to dismiss the complaint on the ground that a preliminary hearing had not been held within the time required by UMDDL. Upon respondent’s overruling his motion, relator filed for mandamus in this court, to obtain an order compelling the magistrate to grant a preliminary hearing or dismiss the complaint.
This court pointed out that the 1959 UMDDL was not applicable to complaints pending in magistrate courts, as held in Turley, supra, and that, while the 1971 amendments, effective September 28, 1971, made the law applicable to complaints, this court had, in the interim, received certified copies from the magistrate court that a preliminary hearing was afforded relator on November 4, 1971, some five weeks bеfore we handed down our decision. The issue was therefore moot, the court ruled, as defendant had received what he had requested — a preliminary hearing. That is not true in the case at bar, where relator is contending the court has lost jurisdiction altogether.
The general assembly in 1971, after the opinion in Turley, amended the UMDDL. Section 222.080 prior to the 1971 amendment read “final disposition of any untried indictment or information,” § 222.080, RSMo 1969, and now reads “final disposition of any untried indictment, information or complaint.” Section 222.080. Section 222.100 prior to the 1971 amendment read “the indictment or information shall be brought to trial,” § 222.100, RSMo 1969, and now reads “the indictment, information, or complaint shall be brought to trial.” Section 222.100.

“In construing statutes to ascertain legislative intent it is presumed the legislature is aware of the interpretation of existing statutes placed upon them by the state appellate courts, and that in amending a statute or in enacting a new one on the same subject, it is ordinarily the intent of the legislature to effect some change in the existing law. If this were not so the legislature would be accomplishing nothing, and legislatures are not presumed to have intended a useless act.”
Kilbane v. Director of the Department of Revenue,
The state concedes that the UMDDL wаs amended in response to the Turley decision. But, it points out, § 222.100 cannot be applied as written because a felony charge cannot be brought to trial on a complaint. Therefore, it argues, the terms “final disposition” in § 222.080 and “trial” in § 222.100 when used in reference to a complaint should be construed as meaning preliminary hearing.
In Missouri, a criminal prosecution on a felony charge is commenced by indictment or complaint. Rule 22.01. If the prosecution is commenced by a complaint and defendаnt is bound over at the preliminary hearing, “all papers in the proceeding” must be transmitted to the court having jurisdiction. Rule 22.07(c). The way a complaint is brought to final disposition is by a preliminary hearing at which the defendant either 1) is discharged or 2) is bound over, an information filed, and a trial held on that information. The information must be filed not later than ten days after the date of order requiring defendant to answer the charge. Rule 23.03. A complaint which ripens into an information is not at an end following the preliminary hearing. No final disposition of the charge against the defendant occurs until trial is held.
If the detainer is filed during the complaint stage, all a defendant can do is ask for disposition of all untried charges underlying the detainer. Defendant has no means of knowing whether a complaint will ripen into an information. But, he does know that for it to do so, there must first be a processing of the complaint and that means a preliminary hearing followed by the filing of an information if he is to be prosecuted further under the complаint on which the detainer was lodged. Therefore, when he asks for a final disposition of the detainer he is asking for disposition of the complaint and all that follows if the complaint is found warranted.
The primary rule of statutory construction is to ascertain and give effect to the legislative intent. This court must look to the object to be accomplished and the problems to be remedied by the statute.
Mashak v. Poelker,
*359
Another basic principle of statutory construction is that statutes relating to the same subject matter, such as the intrastate disposition of detainers law, §§ 222.-080-.150 and the interstate agreement on detainers, §§ 222.160-.260, are in pari materia and must be considered together. State v.
Kraus,
In
State ex rel. Hammett v. McKenzie,
Section 222.140 of the UMDDL states that the “law shall be construed so as to effectuate its general purpose to make uniform the law of those states which enact it.” Therefore, cases which have interpreted this provision in the other jurisdictions which have adopted the uniform act,
see
note 3, are valuable for interpreting the statute.
See State v. Anderson,
In
People v. Lopez,
The interpretation urged by the state, in addition to being contrary to the plain language of the statute, would be contrary to the decisions set out above, and, even more important, would be contrary to the public policy reasons for the law. Under the state’s interpretation, the state would have two 180 day periods in which to bring a prisoner charged by complaint to trial (complaint to preliminary hearing, 180 days; information to trial, 180 days). This interpretation does not forward a swift disposition of detainers. This would extend the time during which the untried state charges could be held over the head of an inmate and affect the conditions of imprisonment. It would be repugnant to the spirit and focus of the law which is to bring about a prompt disposition of the detainer. We do not believe that the legislature in enacting this special statute to deal with the specific problems created by the detain-ers would intend such a result.
See State v. Bey,
Furthermore, if the prisoner were charged by indictment as permitted by Rule 22.01, the state would be limited to one 180 day period to bring him to trial.
See Russell v. State,
Because the state failed to bring relator to trial within 180 days of receipt of his request for disposition and did not, for good cause shown in open court, extend that period, the trial court is without jurisdiction to hear the case. Section 222.100.
Our decision does not handicap or hamstring the prosecution. The written request by the prisoner is fair notice to the prosecutor that, if he plans to file and try an information if defendant is bound over, he should proceed with the necessary preliminary steps and the trial, all within 180 days or should avail himself of the saving provisions in the statute. The prosecution is not *361 locked into commencing trial within a 180 day period no matter what the situation may be. If there are valid reasons why the prosecution cannot meet the deadline, the рrosecutor is not helpless. Section 222.100 provides means for the state to obtain additional time beyond the 180 days in which to bring defendant to trial. The trial court is authorized to extend the time “for good cause shown in open court.” It also permits a continuance on stipulation or on notice to the attorney of record.
The trial court having lost subject matter jurisdiction by operation of law, § 222.100, our preliminary rule in prohibition is made absolute and the trial court shall issue its order dismissing the information with prеjudice.

State v.
Richmond,
The statute is not one which was enacted solely for the benefit of the defendant, but is also fоr the benefit of society. A speedy trial may indeed work against the interests of the defendant. In many cases, the defendant would postpone the trial as long as he could. Society, however, always has an interest in the expeditious disposition of criminal accusations.

See also Barker v. Wingo,
. As noted earlier, in 1971 the legislature amended the law to include a complaint, as well as indictment and information. Turley’s case was prior to the amendment.
. The same is true in Missouri. The records in associate court are trаnsmitted to the circuit court if the defendant is bound over. Rule 22.07(c). The complaint is the first step. When the defendant is bound over, it means there is probable cause to believe defendant *360 has committed a felony. The chain of events started by the complaint has not come to an end. Defendant is not free to go. He must now answer in circuit court. As the Colorado court said, it is a continuous proceeding. The matter has passed from a complaint which can be made by a layman to an official charge, but it grows out of the original complaint.
