unicameral

adj

1. (not-comparable)Of, or having, a single legislative chamber.

   “Those who criticize bicameralism stress that a unicameral legislature will be more efficient and faster in taking decisions.”

   “[W]e could define a national parliament broadly as a Member State's central representative assembly which elects or at least dismisses the national government, and which holds it to account. This seems to be a robust definition comprising the unicameral parliaments, the lower chambers of the bicameral parliaments and the senates with censure powers in the EU Member States.”

   “In 1951 New Zealand's parliament was converted into a unicameral one with the abolition of the upper, nominated chamber, the Legislative Council.”

2. (not-comparable)Of a script or typeface: making no distinction between upper and lower case, but rather having only one case.

   “In the ancient world, Greek was written in a script that was unicameral and atonic. It consisted of a single set of forms – the ones we now regard as upper case. There was little or no punctuation, and there were no diacritics.”
