No Error When Judge Discharged Foreperson Who Refused to Reasonably Participate in Deliberations & Introduced Extraneous Matters

Here is link to advanced opinion of Connecticut Supreme Court decision finding no error where trial judge excused the foreperson during deliberations:

A juror accused another juror (the foreperson) of refusing to speak with other jurors, sitting away from a table where the jury was assembled, and commenting that she was just there to observe. (How did this person become the foreperson???)  Eleven jurors confirmed in questioning by the judge that the foreperson was not participating in deliberations.  The foreperson had also speculated that witnesses were bribed, of which there was no evidence.

Juror Dismissed for Visiting Horse That was Subject of Trial

In an animal cruelty trial a juror visited a boarding facility where a horse that was the subject of the case was being boarded.  This was clearly a violation of the judge's instructions. The juror was dismissed but a mistrial was denied.
