Prince Harry ignored a question on whether he had spoken with King Charles as he walked into the Court of Appeal this morning.
The Duke of Sussex landed in the UK on Sunday ahead of the two-day hearing.
When approached by a reporter outside the court who asked, "Did you speak to your dad?", Harry did not respond.
The question referred to King Charles, who has departed for a four-day diplomatic trip to Italy with Queen Camilla.

The father and son are unlikely to have met during the brief window between their flights.
Harry is taking legal action against the Home Office over a decision made by the Executive Committee for the Protection of Royalty and Public Figures in February 2020.
The dispute concerns the level of police protection he should receive when in the UK.
The Duke has argued that his children, Prince Archie and Princess Lilibet, cannot "feel at home" or "safe" in the country unless his police protection is fully restored.

The hearing will take place across today and Wednesday.
The High Court previously heard that Harry's "status" had changed as a result of no longer being a "full-time working member of the Royal Family".
This change in status forms a key part of the security dispute that has brought the Duke to court this week.
Meanwhile, King Charles and Queen Camilla have arrived in Rome for their state visit aimed at strengthening Britain's relationship with Italy.
