MOSCOW — President Boris N. Yeltsin closed a grueling 14-day session of Russia's highest legislative body Tuesday by chastising lawmakers for leaving the country with a constitutional crisis and without a desperately needed land reform program.

While criticizing the Congress of People's Deputies, the national Parliament, for trying to sabotage his radical reforms, Yeltsin made it clear he considers himself--and his reforms--victorious.

The central issue of the Congress was a bitter power struggle between Yeltsin's radical government and the Parliament, which was elected two years ago and is much more conservative.

Yeltsin's team of ministers had threatened to resign because of the dispute, but through behind-the-scenes maneuvering, Yeltsin, who also holds the job of prime minister, managed to preserve his government's power and avoid what would have been a major setback for Russia's reforms.

He said lawmakers' "uncivilized" conduct had sparked panic at home and put at risk pledges of billions of dollars of Western aid, which Russia needs to change its terminally ill socialist economy into a healthy free-market system.

"It is highly embarrassing when angry and openly provocative phraseology--full of hatred and arrogance--resounds throughout the world from the hall where the supreme legislative body of Russia is in session," Yeltsin fumed. "This phraseology not only destabilizes life in Russia but also complicates our dialogues with near and distant foreign countries."

All the time spent on mudslinging, Yeltsin said, had kept them from making necessary decisions on essential economic issues such as land reform.

Yeltsin did, however, praise lawmakers for finding "the strength in themselves to oppose attempts at a conservative revenge" by Communist hard-liners.

Had their "all-out attack" succeeded, it would have been "equal to a suicide" for the country's reforms, he said.

But the peace reached between the executive and legislative branches is "only a fragile compromise," Yeltsin warned.

The situation is especially shaky, he said, because the Congress failed to pass a new constitution, which would have separated powers in the branches of government.

Before the Congress opened, top government officials predicted that it would adopt, at least in principle, a new democratic Russian constitution to replace the existing Soviet-era document.
