The answer to this is “no”.
Quoracy means that a sufficient number of voting members are present to be able to make a decision on behalf of the whole. In a governing body committee this might be set at 2/3rds of the full committee strength.
In theory, I suppose, if you had a committee of one then the meeting could be quorate with one person – however this isn’t really a committee – more a dictatorship!
Even if there are two people on the committee then one person is simply not enough. For one it doesn’t meet the “2/3rds strength” common practice, and secondly I would argue if there are two people on a committee (a small enough number as it is) that’s probably because both need to make decisions together.
