The Federation Council adjusted its house regulations after the appearance of two new constituent territories and four Federation Council members representing Crimea and Sevastopol.
Regulations Committee Chairman Vadim Tyulpanov told the house the number of Russian constituent territories had grown to 85.
"Therefore we have to adjust the regulations: from now on we will have 170 senators instead of 166 - two representatives of the legislative body of Crimea and the same number from Sevastopol," Tyulpanov said.
Another adjustment to the regulations says that federal laws can now be passed with over "86 votes of senators", while the adoption of constitutional laws requires 128 votes or more, he said.
The Federation Council administration is negotiating with the authorities of Crimea and Sevastopol, Federation Council Chairperson Valentina Matviyenko said.
"We are expecting four senators from the two new constituent territories of the Russian Federation shortly, within the framework of current laws on the formation of the Federation Council," Matviyenko concluded.
Russia's regional administrative division is complicated. Experts say this complex state administration system is a legacy of the Russian Empire and the Soviet Union.
