Short answer. Yes, within limits. Rule 133, Section 7 lets the court stop further testimony on a particular point once the evidence on it is already so full that additional witnesses could not reasonably be expected to add persuasive value, but the rule itself cautions that this power must be exercised with caution.
What the law says
The court may stop the introduction of further testimony upon any particular point when the evidence upon it is already so full that more witnesses to the same point cannot be reasonably expected to be additionally persuasive. This power shall be exercised with caution.

Why courts have this power at all
Trials operate under real time and resource constraints, and a party is not entitled to call an unlimited number of witnesses to establish a single fact once that fact has already been thoroughly proven. If five witnesses would each say essentially the same thing about the same point, calling all five serves diminishing returns for the court's understanding of the case while consuming hearing time that could go to genuinely contested issues. Section 7 gives the court authority to recognize when a point has already been established beyond what additional, cumulative witnesses could meaningfully add.
What triggers the power, and what does not
The standard is specific: the evidence on the particular point must already be "so full" that more witnesses to that same point "cannot be reasonably expected to be additionally persuasive." That is a meaningfully high bar — it is not enough that two witnesses have already testified to something; the point has to already be so thoroughly and convincingly established that further repetition would add nothing of value. A party whose witnesses would each bring a genuinely different angle, additional detail, or independent corroboration on a contested point is not simply presenting cumulative evidence, even if they touch on the same general subject.
Why the rule builds in its own warning
The section does not stop at granting the power — it explicitly says that power "shall be exercised with caution," a built-in reminder that cutting off testimony risks silencing evidence a party has a genuine right to present, particularly on contested or close factual questions where a court's own sense that a point is "already proven" can turn out to be premature. That caution matters most where the point being cut off is central to the case rather than peripheral, since an overly aggressive use of this power can deprive a party of a fair opportunity to fully present its evidence and risks being challenged later as an abuse of discretion.
