The Crown says disgraced former MP Phillip Field was aware from an early stage that police were likely to investigate his dealings with Thai tradespeople.
Field says he did not receive a fair trial and has asked the Court of Appeal to overturn his convictions for bribery and corruption as an MP.
He was jailed for six years in October last year after a jury found him guilty of 11 charges of bribery and corruption as an MP, and 15 of attempting to prevent the cause of justice.
The charges related to free labour he accepted from Thai tradespeople he helped with immigration matters.
Field's lawyer told the Court of Appeal on Tuesday her client was not told papers from a government-ordered inquiry into Field would be handed to police.
However, Crown prosecutor Simon Moore told the court on Wednesday that various statements from Field and others showed he was well aware even before the Ingram inquiry that police would take an interest in the matter.
The Ingram inquiry began in 2005 and took nearly a year to complete.
