ALBANY – An effort to override a number of Governor Pataki’s vetoes will be at the top of the agenda as members of the Assembly and Senate return to the Capitol today for a one- or two-day session.

Among the vetoes most likely to go down is the one rejecting a plan to overhaul the state’s notoriously gridlocked budget process, which has produced late budgets 20 years in a row.

Lawmakers are also considering overruling the Republican governor on a $2 increase in the state’s hourly minimum wage and on a plan to collect taxes from Indian reservations that sell tobacco and gasoline to non-Indians.

Legislative leaders were also negotiating privately toward deals on other loose ends they could tie up before the New Year, such as authorization for expanding the Javits Convention Center on the West Side of Manhattan and restoring some of the funding that Mr. Pataki vetoed from the $103 billion budget they approved in August.

As usual, the top leaders were keeping their precise plans to themselves, declining to disclose exactly what bills they would ask their members to approve today and tomorrow.

“Right now that’s still being discussed,” a spokesman for the Assembly Democrats, Charles Carrier, said yesterday when asked about the agenda. “At this point we don’t have anything firm.”

A spokesman for the Senate Republicans, John McArdle, echoed that idea: “Everything is still up in the air,” he said. “We have not resolved some of the key things that bring us back, principally budget reform.”

The Senate majority leader, Joseph Bruno, previously said he was prepared to override Mr. Pataki on the budget issue, but only if he was unable to negotiate a compromise before the end of this year.

All of Mr. Pataki’s vetoes from this calendar year are theoretically subject to override through December 31.

The Assembly and the Senate unanimously approved the budget reform legislation earlier this year, saying it would guarantee the state never again started a fiscal year without a spending plan in place. Among other things, the package would push back the start of the fiscal year by one month, to May 1; automatically put in place a contingency budget, based on the previous year’s spending, when lawmakers miss that deadline, and create an “independent budget office,” appointed by legislative leaders, to referee disputes over spending estimates and revenue forecasting.

Most provisions of the proposal would not take effect unless voters approve an accompanying constitutional amendment in November.

Mr. Pataki rejected the plan, saying it would shift too much discretion over financial affairs to the Legislature from the governor.

The package was supported by the League of Women Voters, Common Cause, and the New York Public Interest Research Group; it was opposed by the Citizens Budget Commission and the Business Council of New York State.

The minimum-wage plan would gradually increase the current rate by $2 an hour, to $7.15 by January 2007. The Assembly already approved an override, and the Working Families Party, a leading proponent of the measure, expressed confidence last week that the Senate would follow suit. However, Senate officials were contemplating delaying a vote on the issue until later in December, to give them more time to negotiate a compromise with Mr. Pataki, according to an official of the Business Council, Elliott Shaw.

Proponents of collecting taxes from Indian retailers were also hopeful of an override, citing favorable comments from some Republican senators. Mr. Pataki has avoided enforcing similar legislation in the past, saying he prefers to resolve tax disputes as part of broader negotiations with Indian tribes over casino rights and land claims.

Mr. McArdle said legislative leaders were also discussing proposals to reform the state’s Rockefeller-era drug laws, which include some of the harshest penalties of any state, but had not reached agreement as of yesterday.
