OPINION
The relator was indicted in Dallas County for the offense of capital murder. The State elected not to seek the death penalty. During pretrial proceedings, the relator “indicated that [he] seeks to present the testimony of a mental health expert in regards to [his] mental state and the vol-
The relator has now filed an application for writ of prohibition in this Court, seeking relief from the trial court’s order subjecting him to examination by the State’s expert. 2 The relator argues that the trial court’s order impinges upon his Fifth and Fourteenth Amendment right to be free from compelled self-incrimination. He argues that the authorities cited by the State in support of the trial court’s order are factually distinguishable from his case, and that none expressly permits the examination by a State’s expert under the circumstances presented here. Because we find that the relator has failed to satisfy at least one of the criteria for obtaining extraordinary relief, we deny his application.
STANDARD FOR EXTRAORDINARY RELIEF
The traditional test for determining whether mandamus or prohibition relief is appropriate requires the relator to establish two things. 3 First, he must show that he has no adequate remedy at law to redress the harm that he alleges will ensue if the act he wishes to prohibit is carried out. 4 Second, he must show that the act he seeks to compel or prohibit does not involve a discretionary or judicial decision. 5 If the relator fails to satisfy either aspect of this two-part test, then relief should be denied. As to the latter requirement, we have said that it is satisfied if the relator can show he has “a dear right to the relief sought” — that is to say, “when the facts and circumstances dictate but one rational decision” under unequivocal, well-settled (ie., from extant statutory, constitutional, or case law sources), and clearly controlling legal principles. 6
APPLICATION OF LAW TO FACT
For the proposition that it should be allowed to have its expert examine the relator, the State invoked our opinion in Lagrone v. State. 10 The relator argues that Lagrone is distinguishable because there, the defendant proposed to introduce expert testimony with respect to the issue of future dangerousness in a capital case in which the State sought the death penalty. The State responds that the particular factual context matters little-the principle is the same, namely, that once a criminal defendant constructively testifies by submitting to an examination in support of his own testifying expert’s opinion, he has waived his Fifth and Fourteenth Amendment privilege against self-incrimination, and so must choose either to submit to an examination by the State’s expert as well or else have his own expert’s testimony excluded from evidence.
In support of its argument, the State cites this Court’s unpublished opinion in Ward v. State. 11 There we unanimously held, citing Lagrone and Chamberlain v. State, 12 that the operative principle was one of waiver of the Fifth and Fourteenth Amendment privilege, and that it was not limited to the factual context of rebutting expert testimony from the defense with respect to future dangerousness. We articulated the principle thus:
[I]f a defendant breaks his silence to speak to his own psychiatric expert and introduces that testimony which is based on such interview, he has constructively taken the stand and waived his fifth amendment right to refuse to submit to the state’s psychiatric experts. The focus is on the defendant’s choice to break his silence. * * * The issue is whether the psychiatric testimony he intended to introduce was based on his own participation in the psychiatric testing and examination. 13
Focusing on the waiver, we held that the holding of
Lagrone
applied equally to psychiatric evidence in mitigation of the death penalty. “The nature of the psychiatric testimony to be presented is immaterial- — ■
We do not now rely on our unpublished opinion in Ward for the proposition that the trial court did not err to grant the State’s motion for its own psychiatric examination in the factual context of this non-death capital prosecution. But we do regard it as ample evidence that the issue is — at best — an “unsettled” legal question. If what we said in Lagrone is not limited in principle to the type of psychiatric evidence presented at the punishment phase of a death-penalty case, it may not be limited in principle to the punishment phase of a capital murder death-penalty trial, or even to death-penalty cases at all. Accordingly, we cannot say under the circumstances of this case — and particularly in view of the tight restrictions the trial court imposed on the State in its order— that the relator has established a clear right to be insulated from examination by a State’s psychiatric expert. 15 In granting the State’s motion in this case, the trial court exercised a manifestly judicial (and not a ministerial) function. 16 Such an “accomplished judicial act” is not subject to the extraordinary remedy of prohibition. 17

. The relief that the relator seeks is more in the nature of a writ of mandamus than a writ of prohibition, since he would have us "undo” an "accomplished judicial act.”

. In his brief in support of his application for writ of prohibition, the relator argues that, in the non-death-penalty context, we should not regard the State's interest in rebutting defense psychiatric testimony to be sufficiently compelling to outweigh the accused's constitutional privilege against self-incrimination. Brief in Support of Application for Writ of Prohibition, at 4-10. Even assuming that such a balancing approach is consistent with the constructive waiver principle we have articulated in our case law (a proposition that is at least debatable), and that we might tentatively agree that the balance should tip in the relator's favor, his contention amounts to no more than an argument for why the unsettled question should ultimately be resolved in his favor. There is no statute or court opinion that yet says so, as the relator's counsel conceded (“I have not found any law on it one way or the other”) at the hearing on the State's motion. The relator’s argument falls far short of establishing the necessary "clear right" to relief.
. The trial court had both subject matter jurisdiction and jurisdiction over the person, we presume, by virtue of the indictment — at least the relator does not argue otherwise. Under some circumstances, we have observed, even a trial court with general jurisdiction may lack
authority
to take a certain action, and sometimes that lack of authority will render its purported action "void.”
