Combine rows based on column value

I would like to combine/delete subsequent rows into one row based on a column value. Any pointers how to achieve this?

Actual Table:

id  type           decision  date
1   submission      2019-07-25T20:33:43.608Z
1   submission      2019-08-05T18:46:06.309Z
1   submission      2019-08-05T20:36:20.630Z
1   judgement   approve 2019-08-07T18:53:41.000Z
1   submission      2019-08-22T17:11:32.430Z
1   judgement   reject  2019-08-27T16:47:02.000Z
1   submission      2019-08-29T16:23:19.868Z
1   judgement   reject  2019-09-03T17:44:58.000Z
1   submission      2019-09-09T23:06:41.652Z
1   judgement   approve 2019-09-12T14:17:55.000Z
2   judgement   approve 2019-09-12T14:17:55.000Z

Expected Output:

id  type           decision  date
1   submission      2019-08-05T20:36:20.630Z
1   judgement   approve 2019-08-07T18:53:41.000Z
1   submission      2019-08-22T17:11:32.430Z
1   judgement   reject  2019-08-27T16:47:02.000Z
1   submission      2019-08-29T16:23:19.868Z
1   judgement   reject  2019-09-03T17:44:58.000Z
1   submission      2019-09-09T23:06:41.652Z
1   judgement   approve 2019-09-12T14:17:55.000Z
