Conn. Practice Book § 43-41

If the defendant is not brought to trial within the

applicable time limit set forth in Sections 43-39

through 43-40A, and, absent good cause shown,

a trial is not commenced within thirty days of the

filing of a motion for speedy trial by the defendant

at any time after such time limit has passed, the

information shall be dismissed with prejudice, on

motion of the defendant filed after the expiration

of such thirty day period. For the purpose of this

section, good cause consists of any one of the

reasons for delay set forth in Section 43-40 or 43-

40A. When good cause for delay exists, the trial

shall commence as soon as is reasonably possible. Failure of the defendant to file a motion to

dismiss prior to the commencement of trial shall

constitute a waiver of the right to dismissal under

these rules.
