Jacek Czaputowicz was speaking to reporters after the Parliamentary Assembly of the Council of Europe last year adopted a resolution calling on Moscow to return the wreckage of the jet.
Russia has refused to hand the wreck back to Poland, claiming that it is continuing to investigate the crash.
On April 10, 2010, a Polish plane carrying then-President Lech Kaczyński, his wife, and 94 others – mostly political and military top brass – crashed while trying to land at a military airport in Smolensk, western Russia.
The Council of Europe’s Parliamentary Assembly last year called on Russia to “hand over the wreckage of the Polish Air Force Tu-154 to the competent Polish authorities without further delay” in a manner that “avoids any further deterioration” of potential evidence.
“The continuing refusal of the Russian authorities to return the wreckage and other evidence constitutes an abuse of rights and has fuelled speculation on the Polish side that Russia has something to hide,” Council of Europe parliamentarians said at the time.
Speaking in Warsaw on Thursday, Czaputowicz said the Parliamentary Assembly resolution called for the plane wreckage to be protected.
He added: "Despite the resolution, we are seeing disturbing actions around the crash site, ideas emerging for the construction of a gas pipeline running through the crash site.”
The Council of Europe is a human rights organisation. Its parliamentary arm groups representatives of parliaments from the council’s member states.
According to a commission set up by Poland’s Law and Justice party after it came to power in late 2015, the presidential plane was probably destroyed by a mid-air explosion, and Russian air traffic controllers deliberately misled Polish pilots about their location as the jet was approaching the runway.
