A month after a Toronto defence lawyer was arrested at a Brampton courthouse and accused of smuggling drugs, two of the four charges she was facing have been dropped.

On Feb. 12, Peel Regional Police issued a news release indicating that Laura Liscio had been charged with possession of a controlled substance, possession for the purpose of trafficking, breach of trust and obstruction of justice.

Police later revealed that Liscio had been arrested in her courtroom attire. After her arrest, she was escorted to a marked police cruiser alongside uniformed and plainclothes officers.

On Thursday, the obstruction of justice and breach of trust charges against Liscio were dropped. She is still facing charges of possession and trafficking in marijuana.

The allegations against Liscio have not been proven in court.

Her lawyer has said Liscio was passing clothing to a client at a trial when she was arrested.

On Thursday, her lawyer, Stephen Bernstein, told CBC News that Liscio is innocent of any wrongdoing and he is confident she is "not guilty of anything."

He predicted that the dropped charges were the start of a process that will see his client exonerated.

"It is the first step in what will be the total exoneration of Ms. Liscio," Stephen Bernstein said in an interview.

He added: "We have an innocent person here, whose career has been put in jeopardy by allegations that simply are not in fact."

The case has caused outrage in the legal community. Dozens of lawyers have written letters in support of Liscio.
