Which of these events is a ground on which the court may dissolve a firm under section 44 of the Indian Partnership Act, 1932, rather than one that dissolves it without a court order?

Section 44(a) of the Indian Partnership Act, 1932 lets the court dissolve a firm, on a suit by a partner or the next friend, where a partner has become of unsound mind. The other events are contingencies under section 42 on which a firm is dissolved, subject to contract, without any court order: expiry of the term, death and adjudication of a partner as an insolvent.
