A more than 10-year battle Daniel Sabo has had with the Geological Survey of Canada (GSC) continued Monday in the Yukon Court of Appeal.

Sabo is appealing a 2011 Yukon Supreme Court decision which dismissed his $12-million claim against the federal government, five GSC employees, an RCMP officer and a metallurgical expert over a meteorite he found in 1986.

Sabo has maintained the GSC replaced the meteorite he found with a replica and took the life form that was growing on it.

The case he presented to the court in 2010 also claimed RCMP Cpl. Dan Parlee failed to properly investigate his case, and that forensics expert Bill Schneck, who was hired by Sabo's former lawyer, tampered with the rock without his permission.

Sabo is now representing himself in the case and on Monday, brought his case to the appeals court.

Throughout his presentation, Sabo relied on the factom he had given to the court.

Sabo pointed to photos showing the rock before and after it was returned to him.

He argued a date stamp on one photo shows the GSC sliced into the rock before it had his permission to do so. He also argued the agency obtained his permission only "under duress”.

During his earlier court hearing, it was learned Sabo found the rock while he was working on his placer claim near Mayo.

An assaying company in B.C. agreed it was likely a meteorite, though the International Meteorite Society is the only company which can certify that.

In 1998, Sabo noticed a green formation on it.

Scientists with the GSC concluded the growth could be a natural result of oxidation of minerals in the rock, a salt-type crystal or a type of lichen.

The rock was sent to the GSC in Ottawa to be analyzed and later polished with the small cut taken off for more detailed study.

Sabo has continually argued that the GSC kept his rock, replacing it with a replica.

While Sabo has estimated the rock's value at $12.1 million, Alexander Benitah, who's representing the Attorney General of Canada in the case, pointed to estimates that had it come in between $1,000 and $2,500 based on the evidence of the GSC.

He argued Sabo's valuation is based solely on the highest-priced meteorite Sabo found on the Internet, while the $1,000 to $2,500 is based on the evidence of the GSC.

Benitah argued there's simply no evidence to support Sabo's claim and asked that the appeal be dismissed.

Justices Harvey Groberman, Christopher Hinkson and David Harris have reserved their decision on the matter.
