MONTREAL - Despite having killed and decapitated his parents with an axe in 2007, Alain Piche will still get his inheritance after Quebec's Court of Appeal overturned a 2008 Superior Court decision by Judge Ivan Godin.

The decision was based on the Civil Code, which states that a person cannot claim an inheritance if they are found guilty of killing the person whose will names the offender as beneficiary.

The three appellate court judges decided that Piche cannot be held responsible for the deaths because his mental condition robbed him of the ability to differentiate between right and wrong.

Piche, a former accountant, remains locked up in Montreal's Pinel Institution and his mental status is to be re-evaluated in August.

In July 2008, Piche was found not criminally responsible for the murder of his parents in March of 2007.

The decapitated bodies of Gaetan and Lucie Piche were found in the freezer of their Trois-Rivieres, Quebec home.

Piche stands to inherit the $300,000 his parents left him in their will.

Piche's cousin Germain Martel said he wanted to read the full decision before commenting on it but said he is shocked by a decision he believes is illogical.

The families of both victims are planning to meet soon to decide whether to take their appeal to the Supreme Court.
