OPINION ON APPELLANT’S AND STATE’S PETITIONS FOR DISCRETIONARY REVIEW
This is a petition for discretionary review following appeal from a denial of relief in a pre-trial writ of habeas corpus. Appellant was indicted for murder and capital murder and his combined bail on these two offenses was set at $550,000.00. Appellant has been in custody continuously on these charges since October 7, 1988. Pursuant to his writ of habeas corpus, a hearing was held on April 7, 1989, and continued on April 10, 1989. At the conclusion of this hearing the trial court reduced the combined bond to $105,000.00. Appeal was taken to the Second Court of Appeals.
Jones v. State,
On appeal it was contended, inter alia, that the habeas court erred in failing to reduce the bond to an amount the undisputed evidence shows appellant could meet, viz: $14,000.00. Both in the habeas court and on appeal appellant argued he was entitled to have his bail set at that amount by operation of Article 17.151, V.A.C.C.P. In relevant part that article provides:
“Sec. 1. A defendant who is detained in jail pending trial of an accusation against him must be released either on personal bond or by reducing the amount *714 of bail required, if the State is not ready for trial of the criminal action for which he is being detained within:
(1) 90 days from the commencement of his detention if he is accused of a felony[.]”
The court of appeals held that the State failed to meet its burden of proof under this provision to show that it was ready for trial within 90 days of the commencement of appellant’s detention. However, the court of appeals also agreed with the State that Article 17.151 “is a constitutionally impermissible infringement on the judicial branch by the legislature” and therefore “suffers similar constitutional defects as noted by the Court of Criminal Appeals in the Speedy Trial Act, article 32A.02.”
We granted appellant’s petition for discretionary review to address the constitutionality of Article 17.151, supra. Tex.R. App.Pro., Rule 200(c)(1), (2) & (4). We also granted the State’s petition for discretionary review to consider whether the court of appeals erred in holding the State failed to meet its burden to prove it was ready for trial within the statutorily allotted 90 days. Rule 200(c)(2), supra.
I.
To the extent the court of appeals relied upon the Austin court’s holding in Ex parte Danziger, supra, we believe it was in error. 1
Both Article 32A.02 and Article 17.151 were promulgated by the 65th Legislature in Senate Bill 1043. See Acts 1977, 65th leg., ch. 787, pp. 1970 & 1972, §§ 1 & 2, eff. July 1, 1978. The bill contains no sever-ability clause. Even so, should part of the bill be held invalid, as
Meshell
did, “the remainder of the statute must be sustained if it is complete in itself and capable of being executed in accordance with the intent wholly independent of that which has been rejected.”
Tussey v. State,
“ ... Invalidity of a part [of a legislative enactment] does not necessarily destroy the entire act, unless the valid part is so intermingled with all parts of the act so as to make it impossible to separate them, and so as to preclude the presumption that the legislature would have passed the act anyhow.”
Article 32A.02 was enacted in § 1 of Senate Bill 1043. In § 4 of Senate Bill 1043 the Legislature also enacted Article 28.061, V.A.C.C.P. In Meshell the Court found Article 28.061 to be “the enforcement mechanism” for Article 32A.02, and concluded on that basis that the Legislature would not have promulgated one without the other. Thus, Article 28.061 was ruled *715 invalid by virtue of the unconstitutionality of Article 32A.02. Article 17.151 was enacted in § 2 of House Bill 1043. In our view, however, unlike Article 28.061, Article 17.151 can be given effect wholly independently of Article 32A.02, without hindering or distorting the obvious legislative intent to provide assurance that an accused will not be held in custody indefinitely while the State is not at least prepared to bring him to trial. We hold that Article 17.151 was not effectively struck down by our opinion in Meshell simply because it was contained in the same Senate Bill. To the extent it held otherwise, the opinion of the Austin Court of Appeals in Ex parte Danziger, supra, is overruled.
It remains to determine whether Article 17.151 is itself unconstitutional for the same reason we held Article 32A.02 to be, viz: that in enacting it the Legislature encroached upon the prosecutor’s discretion, as a judicial officer, in the preparation of cases for trial, in violation of Article II, § 1, supra.
II.
In
Meshell v. State,
supra, this Court held that under Article II, § 1, “the Legislature may not remove or abridge a district or county attorney’s exclusive prosecutorial function, unless authorized by an express constitutional provision.”
In the instant cause the court of appeals reasoned that Article 17.151 similarly “encroaches on the prosecution’s discretion in the preparation of cases for trial because it forces the county and district attorneys of this state to either bring criminal prosecutions within a short period of time or allow the release of those defendants upon any bail, however low, that such defendants can afford.” Jones v. State, supra, at 510. It does so without any consideration of whether 1) there may be some good reason for delay, 2) the defendant has requested a speedy trial, or 3) defendant has suffered prejudice to his cause on account of delay. Indeed, the court of appeals believed, in some respects Article 17.151 “is a tighter constraint on the prosecutor’s discretion than those contained in” Article 32A.02, in that the latter at least provided, in its subsection 4(6), “for some circumstances under which a delay would not require discharge of the defendant.” Jones v. State, supra, at 510 & n. 4.
The State now reiterates that Article 17.-151 violates separation of powers inasmuch as, like Article 32A.02, it penalizes the dilatory prosecutor without accounting for the above factors relating his dilatoriness to a violation of the constitutional right to speedy trial. Undoubtedly, Article 17.151 may be perceived as to some degree exacting a penalty upon the State’s unpreparedness for trial. Our opinion in Meshell notwithstanding, however, that perception does not end the analysis.
Courts in Texas have recognized two varieties of violation of separation of powers:
“First, it is violated when one branch of government assumes, or is delegated, to whatever degree, a power that is more ‘properly attached’ to another branch. Ex parte Giles,502 S.W.2d 774 , 780 (Tex.Cr.App.1973). The provision [Article II, § 1] is also violated when one branch unduly interferes with another branch so that the other branch cannot effectively exercise its constitutionally assigned powers. Rose v. State,752 S.W.2d 529 , 535 (Tex.Cr.App.1987); Me- *716 shell v. State, [supra, at] 252 ...; see 16 C.J.S. Constitutional Law § 112 (1984).”
Armadillo Bail Bonds v. State,
“The power and authority of a state legislature is plenary and its extent is limited only by the express or implied restrictions thereon contained in or necessarily arising from the Constitution itself.”
Government Services Insurance Underwriters v. Jones,
In our view Article 17.151 does not interfere unduly with the prosecutor’s function. Contrary to the belief of the court of appeals, Article 17.151 actually represents far less of a constraint upon prosecutorial discretion than did Article 32A.02. A prosecutor unprepared within the time limits of Article 32A.02 stood to have the prosecution set aside.

By contrast, a prosecutor who is for whatever reason unprepared within the time allotted by Article 17.151 may nevertheless proceed with his case unmolested.

The only consequence is one which must be considered salutary under any accusatory system embracing the presumption of innocence until proven otherwise,
viz:
that an accused as yet untried and unreleased on bond will not suffer “the incidental punitive effect” of incarceration,
Ex parte Green,
We do not mean to suggest an accused has a constitutional right to have bail set at an amount he can meet, under Article I, §§ 11 or 13 of the Texas Constitution. This Court has never so held, and in fact on numerous occasions has remarked that in setting bail, “[t]he ability of accused to make bond is not alone eontrolling[.]” E.g.,
Ex parte Cascio,
Nor do we mean to suggest that Article 17.151 is a particularly efficacious means to its salutary end, since all a prosecutor has to do to prevent release of an accused who has been unable to make bail is to announce ready in a timely fashion, even if trial is thereafter delayed for other rea
*717
sons. Efficacy of a statute,
vel non,
however, is no ground for striking it down as a violation of separation of powers. Cf.
Ferrantello v. State,
Finally, we are not unmindful of the State’s sometimes legitimate concern that an accused released on pretrial bond may pose a danger to society. Cf.
United States v. Salerno,
III.
In its petition for discretionary review the State argues that the court of appeals erred in holding the prosecutor failed to make a prima facie showing of readiness within the applicable 90 day period. Relying upon
Smith v. State,
As the court of appeals noted, this Court “has indicated that cases decided under the Speedy Trial Act (article 32A.02) are instructive on procedures under article 17.-151.
Kernahan v. State,
The State first argues that an announcement that the State “has been” ready “refers to readiness occurring in the past and continuing up to the time the statement was made.” The State contends this statement of past readiness therefore “fell within the 90-day time limit.” Appellant was arrested on October 6, 1988. The prosecutor’s announcement of ready occurred on the second day of the hearing on the writ of habeas corpus, on April 10, 1989. Coming as it did roughly 150 days after appellant’s arrest, this announcement, in isolation, does not exclude the possibility that the State did not become ready until some time anterior to April 10, 1989, but after the lapse of the 90 day period required by Article 17.151, Sec. 1(1), supra.
The State also contends that from the full context of the prosecutor’s statement it is clear he was informing the trial court that the State “has been ready” for trial as of the filing of the indictment in these causes, which occurred on November 8, 1988, well within the 90 days allotted. The prosecutor’s entire statement, as set out in the State’s brief, is as follows.
“Your Honor, with regard to the matter presently being heard for writ,
*718 George Jones, capital murder, and another pending murder case, Your Honor, shortly after this particular matter was brought to the attention of the District Attorney’s Office, around September— excuse me, going into October of 1988, Your Honor, I was assigned to assist Mr. Bob Gill in the prosecution of this particular case, prior to its indictment on November the 8th of 1988.
Working with Mr. Gill, Your Honor, we reviewed the files.
The detective, in connection with this particular matter, Detective SoRelle, with the Fort Worth Police Department, made some efforts and did, in fact, talk with Mr. Eric Brager, also known as Eric Johnson. And subsequent to that talked to George Jones, the Defendant in this particular matter.
And in connection with the State’s readiness, Your Honor, I simply offer for the Court’s consideration my testimony, that subject to Judge Kredell’s availability, his courtroom’s availability, the assignment of this particular case to his court, the State has been ready for trial, at least to begin the jury selection process in this particular matter, and present what evidence was available to the State for purposes of this hearing.”
Prior to this statement by the prosecutor, one of appellant’s attorneys testified at the writ hearing that he had been allowed to review the State’s file. There he discovered the statement of a witness he considered crucial to the State’s ability to make a case against appellant. This witness, Eric Brag-er, was incarcerated in the Chino Institute for Men in Chino, California. Detective SoRelle of the Fort Worth Police Department had taken Brager’s statement in Chino on October 27, 1988. Given this background, the trial court could reasonably have construed the prosecutor’s announcement of ready to relate back to the filing of the indictment on November 8, 1988, by which time the State had interviewed its chief witness, Brager. Such announcement would suffice to establish a prima facie showing of readiness well within the 90 day limit. See
Carter v. State,
Evidence that rebuts a prima facie showing of readiness “may consist of, among other things, a demonstration that the state did not have a key witness or piece of evidence available by the last day of the applicable time limit so that the state was not ready for trial within that time limit.”
Id.,
at 542. See also
Behrend v. State,
Presented with similar circumstances, several courts of appeals have held that
*719
under various provisions of Section 4 of Article 32A.02, absence of a key witness was an “exceptional circumstance” that would toll the running of the statutory period by which the State must prove its readiness. E.g.,
McCartin v. State,
The State cites several cases for the proposition that showing an important witness is unsubpoenaed or temporarily out of pocket does not necessarily mean the State is not ready for trial. It is true that we have held that issuance of subpoenas is not essential to the State’s readiness for trial.
Philen v. State,
Accordingly, the judgment of the court of appeals is reversed and the cause is remanded to the habeas court for further proceedings not inconsistent with this opinion. Motion for rehearing will not be entertained in this cause.
Notes
. We granted petition for discretionary review in
Danziger
in order to decide constitutionality of Article 17.151, supra, but ultimately dismissed the petition as moot when applicant in that case was brought to trial and convicted before we could dispose of the question.
Dan-ziger v. State,
. Moreover, though it was not a part of the Court’s analysis in Meshell, supra, we note that the dismissal mandated by Article 32A.02 was to be "with prejudice” under Article 28.061, supra.
. Whether Article 17.151 "unduly interferes” with what is arguably a uniquely judicial function to set a bail amount "sufficiently high [as] to give assurance that the undertaking will be complied with],]” see Article 17.15(1), is a potentially prickly separation of powers question, but one that is not squarely presented today.
. There is no indication in the record that the State had commenced proceedings to bring Brager to Tarrant County to stand trial in the causes pending against him pursuant to Article 51.14, V.A.C.C.P., Interstate Agreement on De-tainers, to which both Texas and California are party states. See West’s Cal.Ann.Penal Code, § 1389. Nor is it shown that the State ever attempted to subpoena Brager to testify against appellant under Article 24.28, Uniform Act to Secure Attendance of Witnesses from Without State, to which Texas and California are also party states. See West’s Ann.Cal.Penal Code, § 1334.3. See also Article 24.29, V.A.C.C.P., Uniform Act to Secure Rendition of Prisoners in Criminal Proceedings, to which Texas, but not California, is a party state.
