Concerning the Land Purchase (Guarantee Fund) Bill 1935, which according to Bennet would have negatively impacted the rural middle class of which he was a representative, Bennet accused Concannon and her fellow Dublin men of not caring about the people of the country "If Deputy Kelly, Deputy Donnelly or Deputy Mrs. Concannon were asked to apply a retrospective liability of this character to the citizens of Dublin, would they comply with the request?

Concannon went on to vote that the Dail should disagree with the Seanad propose bill with 71 others[16] Though she was a TD as a university representative, she voted with her party to remove University representation from the Dáil, leading one TD to saying, "I am very much surprised to see such a distinguished scholar and such a great contributor to Irish literature as Deputy Mrs. Concannon voting for the disfranchisement of the University that she has so well and so ably represented."-Mr.
