The case that’s been dogging Hollywood heartthrob Johnny Depp and his wife Amber Heard is still unresolved after the latter failed to show up to another court date on Monday.

Ms Heard was scheduled to face the Southport Magistrates Court on Monday morning over an alleged biosecurity breach by the superstar couple earlier this year.

However, Courier Mail journalist Greg Stoltz Tweeted that the actress was neither “seen nor heard” at court, and that the case had been adjourned for the third time.

• Depp dog case adjourned

Heard and Depp’s terriers, Boo and Pistol, made international headlines when Heard and Depp allegedly brought the pampered pooches to the Gold Coast without declaring them to quarantine.

Heard was also a no-show on two previous occasions despite a summons to appear.

She faces possible penalties of up to 10 years’ imprisonment and fines of up to $100,000 for the alleged offences.
