The three lawmakers who lead the New York State Legislature earned as much as $1.1 million combined practicing law in their spare time last year, according to disclosure statements released on Wednesday.

The most prolific of the three was Sheldon Silver, the speaker of the State Assembly, who works for the personal injury firm Weitz & Luxenberg and got at least a $200,000 raise: He reported earning $650,000 to $750,000 from his legal work, a sharp increase from the year before, when he earned $350,000 to $450,000.

State legislators are allowed to hold other jobs outside their legislative duties, which carry a base salary of $79,500. This outside employment was a top area of interest for an anticorruption panel, known as the Moreland Commission, that Gov. Andrew M. Cuomo appointed last summer, which argued that the part-time jobs presented the “risk of criminal behavior.”

As part of its investigation, the commission issued subpoenas to a number of law firms that employ legislators, provoking a showdown that ended only after Mr. Cuomo abruptly shut down the Moreland Commission in late March.
