A few days back, I asked a question - why in reported speech is the present perfect tense sometimes not back shifted to the past perfect tense ? For example:
He said that he has painted the door.
Someone said - "if the situation is still relevant and the results of it can be seen, heard or felt then the present perfect tenses are not back shifted to past perfect tenses." And this was all about indirect speech, and I totally agree with what was said.
Now let's take a case which is not indirect speech. For example:
1) He noticed that he has finished painting the house.
My question is, is this sentence correct under the condition that finishing the painting has some present relevance ?
2) The president learned that the earthquake has caused havoc across the country.
My question is, is this sentence correct under the condition that the earthquake has recently come and the effects of it can still be seen ?
3) I realized that he has left his wallet.
4) It was unclear that she has painted the door.
Are these 4 sentences correct or do I need to use 'had' in place of 'has' ?
